Research Progress of Materials and Detectors for Mid-wave Infrared Quantum Dots
摘要
Abstract
Quantum dots(QDs)are widely used in photoelectric detection,biomedicine,new energy,and other fields because of their quantum limitations,size,and surface effects.Recent years have seen midwave infrared(MWIR)quantum dots(QDs)become a focal point in infrared research.By adjusting and controlling their size,these QDs can extend their absorption wavelengths in the infrared spectrum.Therefore,the successful preparation of infrared QD materials and devices is crucial for infrared imaging,guidance,search,and tracking.This study first introduces the preparation and synthesis technology of five types of MWIR QDs materials,HgSe,HgTe,PbSe,Ag2Se,and HgCdTe,analyzes the size and morphology,lattice fringe,and infrared absorption spectrum characteristics of the QDs,and then summarizes the domestic and foreign MWIR QDs detectors.The device structures and preparation methods of the detector are summarized,and the photoelectric performance parameters,such as responsivity,detectivity,and response time,of the detectors are compared and analyzed.Finally,the development of MWIR QDs was discussed.关键词
