Multi-band SWIR-MWIR-LWIR Type-II superlattice based infrared photodetector
Type-II InAs/GaSb superlattices (T2SLs) has drawn a lot of attention since it was introduced in 1970, especially for infrared detection as a system of multi-interacting quantum wells.

Type II superlattices for infrared detectors and devices [PDF]
Superlattices consisting of combinations of III-V semiconductors with type II band alignments are of interest for infrared applications because their energy gaps can be made smaller than those of any 'natural' III-V compounds.

A Strain-Compensated InGaAs/InGaSb Type-II Superlattice Grown on InAs Substrates for Long-Wavelength Infrared Photodetectors [PDF]
In this paper, the first demonstration of a highly strained In0.8Ga0.2As/In0.2Ga0.8Sb type-II superlattice structure grown on InAs substrates by molecular beam epitaxy (MBE) for long-wavelength infrared detection was reported.

Novel Passivation Approach of InAs/GaSb Superlattice for Mid-Short Wavelength Dual-Color Infrared Detector [PDF]
For higher surface state density of InAs/GaSb type II superlattice materials, it is easy to form conductive oxide layer on the material surface. The first problem to be solved is passivation in the process of preparing infrared devices with InAs/GaSb ...

The use of one-component plasma in the icp-rie etching process of periodic structures for applications in photodetector arrays [PDF]
The paper presents the effect of ICP-RIE etching time using one-component plasma on various parameters of an InAs/GaSb type II superlattice matrix. In the studies, two samples used at different BCl3 gas flow rates were compared and it was found that ...

“N” structure for type-II superlattice photodetectors [PDF]
In the quest to raise the operating temperature and improve the detectivity of type II superlattice (T2SL) photodetectors, we introduce a design approach that we call the “N structure.” N structure aims to improve absorption by manipulating electron and hole wavefunctions that are spatially separated in T2SLs, increasing the absorption while decreasing
