摘要

This work study on the performance characteristics of one kind of nano-optoelectronics device: InGaAs/GaAs very-long-wavelength quantum well infrared photodetector (VLW-QWIP). Based on a professional simulation tool Crosslight APSYS, we have determined the energy band, dark current spectra as well as those of the traditional AlGaAs/GaAs VLW-QWIPs under device operation temperature of 55 K. Larger responsivity and detectivity have been obtained from InGaAs/GaAs VLW-QWIPs due to its higher photoconductive gain and quantum efficiency, offering guidance for nano-optoelectronics device material choosing and optimization.
