A self-consistent algorithm for InGaAs/GaAs strained multi-period Quantum Well Infrared Photodetectors

Abstract

This work presents a self-consistent algorithm for the simulation of responsivity and detectivity of InGaAs/GaAs strained multi-period Quantum Well Infrared Photodetectors. This algorithm takes into account the fundamental mechanisms involved in the InGaAs/GaAs detector detection process. We have calculated a practical InGaAs/GaAs detector by using this algorithm. The obtained results were in good agreement with the experiments at low temperature below 3.5 V.
