The project will develop infrared metallic hot-electron photodetectors for energy and wavelength resolving photodetection. With the varied applications of infrared photodetectors in Australia, the project aims to establish a novel photodiode architecture that harnesses thermal energy through hot-electrons for high speed and broadband photodetection. By enabling energy resolving photodetection, the photodiode will combine research laboratory scale capabilities into a single optical element. Advanced hot-electron absorber materials will be studied. The research outcomes have applications from telecommunications to biotechnology where photodetectors are a critical sensing component, and for metallic hot electrons utilised in photocatalysis.
