Photodetectors are typically fabricated from semiconductors and are used to detect/absorb photons, which are then converted to electrical signals. The interest in this project is related to the detection of infrared radiation with a specific category of these photodetectors, known as quantum dot/well infrared photodetectors (QDIPs/QWIPs). Infrared photodetectors are essential in many industries and some modern applications require devices with enhanced capabilities. High-performance detectors can be used for spectroscopy in medicine, environmental monitoring and chemistry. Imaging scenarios include the identification of military targets and predicting equipment failure.
The aim of this project is to enhance the performance of QWIPs/QDIPs for hyperspectral and multi-colour applications.
