Abstract :
Charge sensitive infrared phototransistors (CSIP) are well known for their capability for response spectrum tuning and single photon detection. In this paper, we established a physical model for a charge sensitive infrared phototransistor operating at 45μm wavelength using the Crosslight Apsys software. Several key physical mechanisms involved such as inter-subband optical transition and resonant tunneling of carriers were applied and fine tuned to obtain a better simulation result.
