Multiphysics modelling of semiconductor devices

TCAD modelling of advanced semiconductor devices is a core research area.

Thin-film transistors, photovoltaics and detectros are modelled and optimized using a variety of commercial packages, capturing simultaneously electrical, thermal, mechanical and optical behaviour.
