摘要：
We theoretically investigate the performance of a II-VI ZnCdSe/ZnSe-based quantum dot infrared photodetector (QDIP) utilizing intersubband hole transitions in the valence band of the QDs to absorb infrared radiation. The analysis starts with the computation of band structure via multi-band effective mass model based on the Luttinger-Kohn Hamiltonian with the inclusion of strain effects. The theoretical formulation is further used to determine the spectral responsivity and dark current characteristics of the QDIP.
