α-Ga2O2 solar-blind detectors

Solar-blind photodetectors are sensitive to wavelengths shorter than 280 nm. These detectors are named “solar-blind” because they only respond to the part of the solar spectrum that is normally absorbed by the atmosphere. This property implies that it is possible to monitor ultraviolet light in daylight with minimal disruption from the environment. Solar-blind photodetectors are therefore an important enabling technology for flame detection, sensing of biological or chemical agents, and communication.

Wide bandgap materials are naturally suited for this applications. Our previous work has shown that α-Ga2O3 is a suitable candidate for the next generation of solar-blind detectors. However little is know about the nanoscale mechanisms of photoconduction in this material.

This research theme aims to improve the performance of α-Ga2O2 solar-blind detectors by conducting an in-depth analysis of the mechanisms that underpin photoconduction.
