As a member of the III-V compound semiconductors family, the growth of ultrathin films of indium antimonide
has attracted a great deal of attention for its use in mid-wavelength infrared detectors (viz., thermal imaging cameras and forward looking infrared systems), magnetic sensors, magneto-resistors, field-effect transistors, photoconductors, and high-speed electronic devices [1-33].
Experimenters used indium antimonide
nanowires to create a transistor-like device that could transform the electrons from a current applied to it into holes--literally empty spaces left when electrons are taken out.
Based on the material by which they are formed, the SWIR market is segmented into indium gallium arsenide (InGaAs), mercury cadmium telluride, lead sulfide, and indium antimonide
. All these materials can operate in the spectral range of SWIR (0.9 um to 3 um) with great efficiency.
His solution was to take a piece of the semiconductor indium antimonide
and shape it into a lopsided tuning fork.
The majority of thermographic cooled cameras on the market today use a detector made from indium antimonide
Each model contains a cooled indium antimonide
(InSb) detector, which enhances the sensitivity of each camera to detect even the smallest gas emissions.
This camera incorporates a cooled indium antimonide
detector that operates in the 3- to 5-pm waveband.

As QWIP photodetector technology is at an early stage of development, the relatively new type-II InAS/Galnsb (Indium Antimonide/Gallium Indium Antimonide
) super lattice structure has potential to be an alternative to MCT in the long wavelength spectrum.
Sensing technologies are expected to go beyond the traditional principles of piezoresistive, capacitive, and inductive, while emerging sensor materials such as silicon carbide (SiC), carbon nanotube (CNT) and indium antimonide
have enabled sensor penetration into new applications.
