Photonic Crystal Enhanced Wavelength Selective, Multi-Colour Quantum Dot Infrared Photodetectors

点击翻译按钮获取中文摘要

Photonic crystal enhanced quantum dot infrared photodetectors are a new generation of detectors developed from integrating nanotechnology with material science and optics. This would not only enhance the detector performance but the structure will now detect a narrow band around the desired wavelength with multi-colour detectivity. The technology developed in this project is anticipated to attract interest from the industries and government agencies. It will be pervasive for use at home, in the manufacturing and mining industry, environmental and pollution monitoring, defence and national security. Applications include spectral imaging, remote sensing, environmental/pollution monitoring, toxic gas and bio-hazardous material detection.
