Emerging electronic devices and circuits

Read about our emerging electronic devices and circuits research.

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.

Device-circuit interaction

We use mixed-mode (TCAD and SPICE) numerical simulations to study the behaviour of electronic circuits which include advanced devices for which compact models have not yet been developed.
