Sentaurus Technology Template: Light-Triggered Thyristor 
PDF IconFull Documentation

This Sentaurus TCAD project simulates the time-dependent switching characteristics of a light-triggered thyristor. In particular, the project investigates if a given light-beam intensity or light-beam radius is sufficient to trigger the thyristor.
