Space exploration requires advanced materials able to withstand high energy particle radiation and extreme temperature gradients. To this effect, resilient photodetectors (PD) are needed with good photo-responsivity from high photon energy (deep ultraviolet) through to the near infrared. Typical PD are based on SiC, for radiation resistance and resilience to the varying temperatures in Space. However, such semiconductors require high deposition temperatures above 1,000 oC. This proof-of-concept project will, uniquely, couple wide band gap gallium oxide (with deposition temperature < 700 oC) with enhanced photo-absorption from antimony sulphide nanorods to enable broadband photodetection for extreme environments.
