Simulation of Dynamic Ionization Effects in 6H-SiC Devices
A numerically robust and physically consistent implementation of the rate equations describing the dynamics of discrete impurity states (deep traps) in the band gap has been accomplished within the framework of an advanced drift-diffusion model. Conceiving the dopants in SiC as such energy states, the impact of long ionization time constants on the device operation has been demonstrated.
