Sub-terahertz photoconduction induced by interpayer transition in an InAs/GaSb-based type II and broken-gap quantum well system
In this paper, we demonstrate theoretically that, when an InAs/GaSb-based type II and broken-gap quantum well is subjected to a light field, conductance can be observed along the growth direction due to charge transfer between electron and hole layers which are spatially separated. A peak profile can be observed in the conductance within sub-terahertz bandwidth. The peak shifts to the lower frequency (red-shift) with increasing temperature and a more broadened peak structure can be observed at...[Show more]
