Inas wavelength
WebAlthough several direct bandgap group III–V materials including InAs, InSb, GaSb, and InAsSb are used for MWIR photodetection, mercury cadmium telluride (MCT or called HgCdTe) which is a group II–VI material has been the most used detector owing to its tunable bandgap spanning the mid-wavelength infrared (MWIR: 3–6 μm), long-wavelength … WebThe results showed that different interface structure can also influence the band structure, leading to the changes of cutoff wavelength. For the same InAs/GaSb superlattice material fully compensated with InSb interface, one with symmetric InSb interfaces has shorter cutoff wavelength than superlattice with asymmetric interfaces. 展开
