Electronic/Optoelectronic Materials and Device Research

We use thermal evaporation, pulsed laser ablation and RF magnetron sputtering  to  fabricate electronic/optoelectronic thin films and devices, including organic light emitting diodes (OLEDs), flexible devices, transistors and photodiodes. 

A focus is contacts, interface phenomena, defects, charge injection and transport, and the correlation with device performance. 

We primarily use XPS, UPS, Photoluminescence/UV-Vis, Raman, HRTEM, Electrical (Hall, C-V, I-V etc.).  State of art facilities are available through MRF.
