A novel quantum effect photodetector array consisted of AlAs/GaAs/InGaAs/GaAs/InAs/ quantum-dots in quantum-well hybrid structure has been tested. It showed a wide response wavelength range from 400nm to 1000nm. The low threshold voltage (−0.8V) and the high responsibility (10A/W) at 77K made it a good choice for optical detection. A custom-made capacitor feedback transimpendance amplifier (CTIA)...
We have designed and developed a field deployable biosensor unit based on a novel proprietary quantum dots-quantum well hybrid structure. We analyzed in detail the detection sensitivity and in particular weak light detection and analysis of the semiconductor optoelectronic device. We designed a readout circuit and a data processing unit to handle the response signal. The sensor unit is equipped with...
