WebInAs/GaSb and InAs/InAsSb type II superlattices have been proposed as promising alternatives to HgCdTe for the photon absorbing layer of an infrared detector. When combined with a barrier layer based on an InAs/AlSb superlattice or a AlSbAs alloy, respectively, they can be used to make diffusion limited "barrier" detectors with ... WebMar 23, 2024 · Thus, we have presented a developed MBE technique for forming the AlSb/InAs heterostructures with the InSb-type heterointerface for the HEMT transistors; the electron mobility at 300 K was 15 000 cm 2 / (V s) at an electron surface density of 1.2 × 10 12 cm –2. The technique for fabricating a HEMT transistor based on the grown ...

WebSep 29, 2012 · This paper reports the use of an InAs/GaSb strained layer superlattice (SLS) as an etch stop layer for GaSb substrate removal with a BCl3/SF6 etch chemistry. Optimum chamber conditions were determined by measuring etch rates and selectivities for two types of superlattices. It was found that selectivity of GaSb over a superlattice is maximized if … WebIndium arsenide, InAs, or indium monoarsenide, is a narrow-bandgap semiconductor composed of indium and arsenic. It has the appearance of grey cubic crystals with a melting point of 942 °C. Indium arsenide is similar in properties to gallium arsenide and is a direct … darwing consultora
