Sentaurus Technology Template: SiC Schottky Diode 

This Sentaurus TCAD simulation project provides a template setup for the simulation of silicon-carbide devices. Special attention is given to the changes in the numeric accuracy settings required to simulate large bandgap materials such as silicon carbide. For the example of a Schottky diode, the forward IV and the reverse breakdown characteristics are simulated.
