Very long wave (> 14μm) infrared quantum cascade detectors based on III-V materials are presented. Thanks to the optimum design of electron transport mechanism, high detectivity is obtained without decreasing device responsivity. For the 14.2 μm QCD, a work temperature up to 82K is obtained with a peak responsivity about 0.95 mA/W and detectivity of 1×108 Jones. Peak responsivities is 2.34 mA/W...
In this paper we report the novel assembly method of a biosensor unit based on 64 pixel photodetector array with a proprietary semiconductor quantum dots (QDs) quantum well (QW) hybrid structure. There is significantly lower dark current for optimized high sensitivity detector. The capacitive trans-impedance amplifier (CTIA)-correlated double sampling (CDS) readout circuit can readout weak optical...
