Abstract
In this paper, the performance of CdS/ZnSe-based quantum well infrared photodetector is studied considering physics-based theoretical modeling. In this model, finite difference method is used to determine eigenenergy states in the quantum well structure. Results show that the absorption coefficient concerning bound-to-bound intersubband transitions using CdS/ZnSe-based QWIP is much larger than III–V-based QWIP like GaAs/AlGaAs. Moreover, multispectral region of infrared operation such as the mid- and long wavelengths of operation is obtained.
