Wide-Bandgap Semiconductor Devices for Power Electronics, Optoelectronics and Sensing
This community develops high-performance electronic and optoelectronic devices using wide-bandgap materials, primarily for power conversion, high-frequency amplification, and ultraviolet detection.
The research centers on the growth and characterization of gallium nitride (GaN), gallium oxide (Ga2O3), and silicon carbide (SiC) thin films. Key device architectures include high-electron-mobility transistors (HEMTs), Schottky barrier diodes, and quantum well structures. Applications span power electronics for renewable energy integration and electric vehicle charging, high-efficiency power amplifiers, and solar-blind photodetectors for security and motion tracking. Methods emphasize molecular beam epitaxy and chemical vapor deposition to achieve high electron mobility and thermal stability in these materials.
The largest share of the community's output is found in gallium research, accounting for 36.9% of all gallium research, and 33,046 papers here. Nitrogen research contributes 17.6% of its total output, with 24,763 papers, and indium research contributes 11.8% of its total output, with 8,720 papers.
The community comprises 54,419 papers, publishing most frequently in Applied Physics Letters, Journal of Applied Physics, and IEEE Transactions on Electron Devices.
Recent work focuses on thermal management strategies for wide-bandgap power semiconductors, high-sensitivity solar-blind photodetectors for motion tracking, and the development of neuromorphic photodetectors and optosynapses using amorphous gallium oxide and GaN heterojunctions.
