Paper Abstract

We have developed a current controlled numerical model by solving the semiconductor device drift-diffusion equations in an isothermal condition to study the current-voltage characteristics of heterostructure GaN/6H-SiC pnpn thyristors. The temperature sensitive parameters such as the density of states, lifetime, mobility, and bandgap energy are included for the electrical characterization. The modeling work is aimed at designing four-layer pnpn thyristors using GaN, 6H- SiC, or combination of thereof, for high power high temperature switching applications. Preliminary simulated results show high power switching at high temperature.
