Our research – Gallium Oxide Optoelectronic Devices

Here are our core activities.

Wide bandgap semiconductor and defect characterisation

We investigate the properties of semiconductors and their defects, and develop several novel approaches to characterise defects in semiconductors. Some examples:

Luminescence properties of dislocations in α-Ga₂O₃
Atomic scale observation of threading dislocations in α-Ga₂O₃
Hydrogen-related 3.8 eV UV luminescence in α-Ga₂O₃

Ultraviolet (UV) detection technologies

We investigate the properties and applications of UV photodetectors. Some examples:

Gallium oxide-based photodetectors for water quality monitoring
Consistent reporting of performances in Ga₂O₃ UV-C photodetectors
Atomic layer deposited α-Ga₂O₃ solar-blind photodetectors

Low-cost production of UV sensing materials

We engineer low-cost methods to produce Ga₂O₃ materials and devices, to help the implementation of UV technologies for everyone.
