Characteristic


Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb).


Chemical formula:InSb

Molar mass:236.578 g·mol−1

Appearance:Dark grey, metallic crystals

Density:5.775 g⋅cm−3

Melting point:527 °C (981 °F; 800 K)

Band gap:0.17 eV

Electron mobility:7.7 mC⋅s⋅g−1 (at 27 °C)

Thermal conductivity:180 mW⋅K−1⋅cm−1 (at 27 °C)

Refractive index (nD):4.0

Crystal structure:Zincblende


Application


Thermal image detectors using photodiodes or photoelectromagnetic detectors

Magnetic field sensors using magnetoresistance or the Hall effect

Fast transistors (in terms of dynamic switching). This is due to the high carrier mobility of InSb.

In some of the detectors of the Infrared Array Camera on the Spitzer Space Telescope
