Indium antimonide

<p>Indium antimonide (InSb) is a crystalline <a href="/facts/Chemical_compound/37FXqqtv">compound</a> made from the <a href="/facts/Chemical_element/0jducgWD">elements</a> <a href="/facts/Indium/zRq3stVb">indium</a> (In) and <a href="/facts/Antimony/YsA7lVgT">antimony</a> (Sb). It is a narrow-<a href="/facts/Band_gap/IjIeh95l">gap</a> <a href="/facts/Semiconductor/zFf3mGTE">semiconductor</a> material from the <a href="/facts/Boron_group/RXnvqnNk">III</a>-<a href="/facts/Nitrogen_group/jX4hvCkK">V</a> group used in <a href="/facts/Infrared_detector/pK7SfsEv">infrared detectors</a>, including <a href="/facts/Thermography/DWxF0CsD">thermal imaging</a> cameras, <a href="/facts/Forward_looking_infrared/00XqYfqo">FLIR</a> systems, <a href="/facts/Infrared_homing/shTBbEmn">infrared homing</a> <a href="/facts/Missile_guidance/NSna0Dtk">missile guidance</a> systems, and in <a href="/facts/Infrared_astronomy/WEmAadyf">infrared astronomy</a>. Indium antimonide detectors are sensitive to infrared wavelengths between 1 and 5 μm.
</p><p>Indium antimonide was a very common detector in the old, single-detector mechanically scanned thermal imaging systems. Another application is as a <a href="/facts/Terahertz_radiation/729QecPK">terahertz radiation</a> source as it is a strong <a href="/facts/Photo%25E2%2580%2593Dember_effect/3tdGnEww">photo-Dember</a> emitter.
