Research interests:

My research topic is based on the development, fabrication, and characterisation of novel Terahertz (THz) devices. Specifically, I am working on the enhancement of THz emission from Low Temperature grown GaAs (LT-GaAs) photoconductive switches by exploring different device geometries. In addition, I am also working on the development of a new THz emitter based on intersubband transitions in multiple quantum wells. The aim is to replace LT-GaAs using a multiple quantum well (MQW) structure where a wide range of parameters can be finely tuned to optimise the essential operating features.

In the area of narrow band THz sources, I am working on the development of a novel terahertz Quantum Cascade Laser (QCL) design based on a new depopulation mechanism which relies on resonant Gamma-X electron transfer. This design may offer improved temperature performance compared to existing THz QCL designs.
