TCAD Simulation of Diamond Static Induction Transistors for Radio Frequency Power Amplifiers
Ultrawide bandgap (UWBG) semiconductors are predicted by various figures-of-merit to outshine the wide bandgap (WBG) semiconductors such as SiC and GaN in power and radio frequency (RF) electronics. Of the UWBG semiconductors, diamond is highly promising for RF application thanks to the ultra-high breakdown electric field (10 MV/cm), highest thermal conductivity (>2000 W/m-K), and carrier mobility (>2000 cm2/V-s). This project aims to study the performance of diamond Static Induction Transistors (SITs) for RF application using TCAD device simulation in Silvaco Atlas. The impact of various device and material parameters was investigated to study the optimal device design space.

Sponsored project | Spring 2024
David McComas’ FURI project is sponsored by TSMC.
TSMC is a global leader in the semiconductor foundry business. The company’s industry-leading process technologies and portfolio of design enablement solutions help its customers and partners unleash semiconductor innovation. With its recent expansion into Phoenix, TSMC sees the benefit of a strong partnership with ASU faculty and student researchers. TSMC supports the FURI program by providing additional funding for exceptional research projects related to the semiconductor industry. FURI student researchers who pursue a project related to the Semiconductor Manufacturing research theme are eligible for this sponsorship. TSMC-supported FURI students receive a $2,600 stipend and $400 to use for materials. Exceptional research proposals that align with the research theme of Semiconductor Manufacturing will be considered for this additional funding.
