Here’s a RoundUp of this month’s must-read news about silicon carbide (SiC), gallium nitride (GaN), and Wide-Bandgap Materials!

SiC News

KERI team corrects 15-year error in global SiC power semiconductor standard

A South Korean research group has, for the first time in almost 15 years, disclosed inaccuracies in the global metric employed to identify flaws in ‘SiC (silicon carbide) power semiconductors’, essential for electric vehicles and renewable energy systems, and has suggested an alternative metric.

The Korea Electrotechnology Research Institute (KERI) declared on the 25th that Senior Researcher Na Moon-kyung from the Next-Generation Semiconductor Research Center, in collaboration with a joint research team led by Hong Soon-gu at Chungnam National University, Horiba STEC Korea, and SK Siltron, has established a criterion for identifying defects within SiC semiconductors.

They effectively reestablished the “true color (specific emission wavelength)” of internal flaws in SiC semiconductors that the global community had misinterpreted for about 15 years. The findings of the study were disseminated in the global publication ‘Acta Materialia’ on September 8.

If “stacking faults” arise, where atoms become slightly misaligned as they accumulate layer by layer during semiconductor manufacturing, the power semiconductor fails to achieve optimal performance, requiring rigorous quality control.

In industry, “photoluminescence (PL) inspection” identifies flaws without damaging the semiconductor wafer. This technique relies on the principle that light emitted from flawed areas, when illuminated, has a different wavelength than that from pristine sections.

The research team found that “Frank-type stacking faults” are the most common defect type by analyzing data from over 100,000 problems across 207 commercial wafers. Frank-type stacking faults arise when an atomic layer within a semiconductor’s crystal lattice is missing or newly introduced. It resembles a cake made of alternating layers of sheets and cream, where an extra layer of cream replaces a sheet.

Mivium Achieves Breakthrough in GaN Nanoparticle Production: Opening New Pathways for High-Performance Semiconductors

Mivium Inc. has reached a notable milestone in materials science: effectively synthesizing high-purity, submicron gallium nitride (GaN) particles using its proprietary, protected technology platform (which also covers other wide-bandgap and advanced semiconductor materials such as gallium oxide and boron nitride).

This innovation addresses a major limitation in wide-bandgap semiconductor production, enabling novel device designs and integration methods once deemed financially impractical.

Independent external evaluation verifies that Mivium has produced phase-pure hexagonal wurtzite GaN particles with a particle size range of 300-500 nanometers, enabling new processing avenues for GaN thin-film applications and substrate manufacturing. The substance demonstrates:

  • Homogeneous particle size distribution within the submicron spectrum
  • Phase-pure polycrystalline configuration (hexagonal wurtzite)
  • An elevated faceted morphology indicating consistent crystal integrity.

Capacity for industrial-scale production. Chandra Deshpandey, PhD, Mivium’s CTO and an emeritus professor of Materials Science and Engineering at UCLA, said no one has proven they can manufacture submicron GaN particles of this quality and scale. The excitement lies not only in attaining submicron particle dimensions but also in establishing phase purity and homogeneity that satisfy semiconductor-grade standards. This creates opportunities for novel device architectures and integration methodologies that were previously unattainable. We are empowering the sector to venture into completely uncharted domains.

In July 2026, Mivium secured $4.23 million through a private-placement financing, elevating its total capital raised to over $10.5 million. The financing facilitates ongoing research and development, materials analysis, thin-film innovation, and collaboration with prospective commercial and strategic allies.

FORTITUDE™: A Fortress of Innovation

FORTITUDE™ is a robust, multifunctional microchip developed by Northrop Grumman, built on gallium nitride (GaN) to deliver accuracy and speed when conventional electronics fall short.

At the heart of advanced sensors, FORTITUDE powers essential detection systems, including radar and surveillance technologies, delivering faster, more precise information when every detail matters. Engineered in high- and low-power variants, it enhances military radars with superior clarity and faster switching, while supporting equipment in extreme conditions such as outer space. This technology is poised to enable ultra-high-frequency communications, opening new spectrum for satellite communication, advanced wireless networks (6G and beyond), and other applications.

FORTITUDE derives its robustness from its proprietary “superlattice” architecture, built like a castle wall, fitting its fortress namesake. Composed of numerous exceedingly thin layers of aluminum-GaN and GaN, each tens of thousands of times thinner than a human hair, it has three components: source, gate, and drain. The gate, resembling a crenelated fortress parapet, regulates electron flow from source to drain, enabling FORTITUDE to retain over 10 times the charge of conventional GaN devices and 100 times that of silicon chips.

Conventional GaN and silicon semiconductors dissipate energy due to resistance, like water flowing sluggishly through constricted, uneven pipes; FORTITUDE integrates GaN’s benefits with advanced silicon-derived structural design to mitigate this loss. This castle design enables effective signal transmission, minimizing energy loss, reducing distortion, and decreasing errors.

The result: clearer signals, better separation of overlapping transmissions, and the ability to manage wide, high-frequency ranges, essential for advanced radar and communication technologies.

World’s First Ampere-Level Vertical Gallium Oxide MOSFET Developed

Gallium oxide is attracting interest for high-voltage, high-efficiency power devices because of its wide bandgap, high breakdown field, and low conduction losses. Nonetheless, obstacles in p-type doping have persistently impeded its advancement for high-power applications and market viability.

Vertical gallium oxide MOSFETs have typically faced limitations in current capacity, breakdown voltage, and leakage current. Jiachi Power Technology, located in Shanghai, has lately reached a significant milestone in this domain. Based in Shanghai’s fourth-generation semiconductor manufacturing hub, the company has completed the initial phase of wafer production and validation for its vertical gallium oxide MOSFET chips.

The team claims to have created the world’s first enhancement-mode vertical gallium oxide MOSFET, with an on-state current exceeding 1 A and a breakdown voltage above 900 V, setting new benchmarks across key performance parameters according to publicly available data.

Consistent, manageable p-type doping has long posed a major global obstacle for high-power gallium oxide MOSFETs. Consequently, earlier research publications and industrial analyses did not report vertical gallium oxide MOSFETs with on-state currents above 1 A, hindering commercialization.

To address this issue, Jiachi has improved both device design and manufacturing techniques. The team developed proprietary MOSFET cell and termination architectures, carefully controlling internal device geometry and electric-field distribution to improve stability and breakdown performance.

Additionally, the firm devised a self-aligned ion implantation technique for the MOSFET channel, addressing challenges in accurate channel formation and consistent dopant control. This study instituted a specialized process flow for high-power gallium oxide devices, succeeded by a comprehensive initial fabrication cycle and electrical assessment.

Quantitative findings showed a threshold voltage of 3.9 V, enabling stable enhancement-mode operation. The device achieved an on-state current of 1.2 A and an on-resistance of 33 mΩ·cm².

Sapphire-grown semiconductor film sets bandgap record

Semiconductors with broader bandgaps may enable more compact, efficient electronic devices that can handle much higher voltages; however, as the bandgap widens, controlling the material’s electrical conductivity becomes increasingly challenging. A research team led by Darrell Schlom at Cornell University has shown that incorporating silicon into aluminum gallium oxide thin films can maintain this control at bandgaps wider than any previously reported semiconductor. The study was published in Nature.

Aluminum gallium oxide is a particularly advantageous substance. By varying the aluminum-to-gallium ratio, researchers can tune the bandgap between 5.4 and 8.6 electronvolts (eV), the broadest range of any recognized semiconductor. However, as aluminum concentration increases, it becomes significantly harder to provide the material with free electrons. Up to this point, aluminum-dense films have shown significantly lower electrical conductivity than gallium-dense films, making them unsuitable for electronic applications.

Schlom’s team addressed this difficulty by employing a meticulous production method utilizing a sapphire substrate. To grow the oxide films, they used molecular-beam epitaxy, which builds a material incrementally, one atomic layer at a time.

As they deposited each film layer on the sapphire, they incorporated small amounts of silicon, whose atoms provide additional electrons to the material. Ultimately, they assessed the bandgaps and electrical characteristics of the films and evaluated their performance within two essential electronic devices: a diode and a transistor.

The silicon-doped films exhibited electrical conductivity at bandgaps over 7 eV, surpassing the former record set by cubic boron nitride. With bandgaps exceeding 6 eV, a range the scientists call “colossal bandgap,” the films showed electrical conductivity at ambient temperature almost 100 million times higher than any prior findings. The diode and transistor functioned effectively with these wide-bandgap materials.

The method may make producing next-generation semiconductors significantly more feasible. Unlike other ultra-wide-bandgap substances such as diamond and cubic boron nitride, sapphire is abundant, inexpensive, and currently produced in high quality and in large quantities.

Hybrid diamond chip strengthens interactions between light and quantum bits

To control interactions between photons and quantum information carriers, researchers created and demonstrated a unique hybrid photonic platform that combines quantum emitters with photonic devices. By connecting quantum devices over long distances, the chip-based platform, which combines gallium phosphide (GaP) with a diamond substrate, may help make quantum networks practical.

Connecting quantum memories, or qubits, over long distances is necessary to scale quantum technology and build communication networks. Converting qubit information into optical photons that can travel through the network is a major challenge, even though fiber-optic networks offer a promising way to do this.

Researchers at Pacific Northwest National Laboratory and Washington University, led by Kai-Mei C. Fu, describe their new hybrid platform in the journal Optica Quantum. They also describe a scalable fabrication process to solve a long-standing problem in producing diamond-based photonic devices. Using this method, they created over 600 GaP nanophotonic cavities on a diamond substrate with a 99.5% yield.

Ultrahigh Interfacial Thermal Conductance across GaN/BAs Interfaces via Atomic-Level Engineering

Combining gallium nitride (GaN) with boron arsenide (BAs) substrates, which have ultrahigh thermal conductivity, offers a potential path to next-generation high-power devices. Thermal dissipation in these integrated systems is primarily governed by thermal conduction at GaN/BAs interfaces, with buffer layers like Al2O3 commonly used to address lattice mismatches and promote heterointegration. Nonetheless, the atomic-level structural elements that influence thermal transport at GaN/BAs interfaces remain poorly understood, hindering advances in interfacial thermal conductance.

The authors present an approach to achieve atomic-scale interfacial structural homogeneity to enhance ultrahigh thermal conductance at GaN/BAs interfaces, using molecular dynamics simulations supplemented by machine-learning interatomic potentials. We show that interfacial structural consistency matters more than individual bond strength in determining thermal transport at the examined GaN/BAs interfaces.

For example, the As-N-terminated coherent interface shows the greatest interfacial structural consistency and achieves an exceptional interfacial thermal conductance of around 2000 MW·m−2·K−1, an almost eightfold improvement over the experimentally observed Al2O3-mediated interface (250 MW·m−2·K−1).

Finite-element analysis suggests that this atomic-scale optimization directly transfers into device-scale performance, resulting in a considerable boost in overall heat dissipation efficiency. These results indicate that improving interfacial structural consistency is a viable approach to achieving superior thermal management efficiency in future high-power electronic systems. 

Perspectives and progress on wurtzite ferroelectrics: Synthesis, characterization, theory, and device applications

Wurtzite ferroelectrics are a novel class of materials that enhance the capabilities and application potential of wide-bandgap semiconductors. Binary wurtzite semiconductors offer significant, adjustable spontaneous polarization; direct band gaps ranging from infrared to ultraviolet; high thermal conductivity and acoustic wave speed; high electron and hole mobility; and minimal optical losses.

The ability to invert polarization in ternary wurtzite semiconductors at ambient temperature enables memory and analog functionality, as well as quasi-phase matching in optical devices, thereby enhancing the wurtzite semiconductor ecosystem, provided the requisite property combinations are achieved for specific applications.

This article reviews progress in designing, synthesizing, and characterizing wurtzite ferroelectric materials and devices. Key features encompass: the direct and quantitative examination of polarization reversal of approximately 135 μC/cm2 charge in Al1−xBxN through electron microscopy, Al1−xBxN ferroelectric domain configurations poled to a width of 400 nm via scanning probe microscopy, and complete polarization retention following more than 1000 h at 200 °C, alongside a twofold increase compared to ZnO in the nonlinear optical response of Zn1−xMgxO.

This work provides an overview of the primary trade-offs, obstacles, and prospects in thin-film deposition, heterostructure design and characterization, and device fabrication.
