Abstract
A InGaSb/GaSb strained-layer superlattices infrared photodetector in which the light-hole and heavy-hole are dispersed by the stress of the lattice mismatch, making the confined energy of the light hole and that of the heavy hole different. The wave function coupling of 1C-1HH is larger at near zero bias, thus the 1C-1HH is dominant. The wave function coupling of 1C-1LH is increased as reverse bias increases. When the reverse bias is high enough, the 1C-1HH transition becomes dominant. Because the transition energy of 1C-1HH and that of 1C-1LH are different, the modes of photodetector can be modulated by applying voltage.
