Maximizing wave function overlap(WFO)within type-II superlattices(T2SL)is demonstrated to be important for improving their photoelectric properties,such as optical transition strength and quantum efficiency,which,howe...
We present a theoretical study on the terahertz (THz) optoelectronic properties of long-period InAs/GaSb type-II super lattices (SLs). The eight-band k·p model is used to calculate the electronic structures of such S...

We present the fabrication of a mid-wavelength infrared focal plane array (FPA) based on type-II InAs/GaSb strain layer superlattices (SLs). The detectors contain a 400-period 8 ML InAs/8 ML GaSb SL active layer, ...
InAs/GaSb type-II superlattce (T2SL) photodetector structures at the MWIR regime were grown by molecular beam epitaxy. The growth temperature and group-V soaking times were optimized with respect to interface and tran...
