Investigation of InAs/GaSb superlattice based nBn detectors and focal plane arrays
… the weight and cost of a infrared system. The InAs/Ga(In)Sb strained layer superlattice (SLS) material system proposed for the IR detection in 1987, has been considered in recent years as an interesting alternative to the present day IR detection technologies. InAs/GaSb SLS has a type II band …

Novel etch studies and passivation techniques on InAs/GaSb superlattice based infrared detectors
… peak wavelength and cost. Type-II band aligned InAs/Ga(In)Sb strained layer superlattice (SLS) material system proposed for the IR detection in the 1970s has been considered in recent years as an interesting alternative to the present day IR detection technologies. Type-II SLS technology …

Theory and Experiment of Antimony-Based Type-Ii Superlattice Infrared Photodetectors
There is currently considerable interest in InAs/InGaSb type-II superlattices because of their broken-gap type-II band alignment, which forms spatially indirect band gaps in the range of 3--30 mum. Combining the advantages of III-V epitaxial growth techniques and high sensitivity to normal incident …

InAs/Ga(In)Sb superlattice based infrared detectors using nBn design
… detectors operating at higher temperatures. InAs/GaSb strained layer superlattice (SLS) photodectors are now considered as a promising technology for both MWIR and LWIR wavelength ranges. The bandgap of the SLS can be adjusted by controlling the thickness of the constituent InAs and GaSb …

Mid-IR type-II InAs/GaSb nanoscale superlattice sensors
… of the whole infrared system. In recent years, InAs/GaSb superlattice based detectors have appeared as an interesting alternative to the present-day IR detector systems. These heterostructures have a type-II band alignment such that the conduction band of InAs layer is lower than the valence …
