Product Description

PAM-XIAMEN offers Compound Semiconductor InSb wafer – Indium antimonide wafer which is grown by LEC(Liquid Encapsulated Czochralski) as epi-ready or mechanical grade with n type, p type or semi-insulating in different orientation(111) or (100). Indium antimonide doped with isoelectronic(such as N doping) can reduce the defect density during the indium antimonide thin films manufacturing process.

Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb). It is a narrow-gap semiconductor material from the III-V group used in infrared detectors, including thermal imaging cameras, FLIR systems, infrared homing missile guidance systems, and in infrared astronomy. The indium antimonide detectors are sensitive between 1–5 µm wavelengths. Indium antimonide was a very common detector in the old, single-detector mechanically scanned thermal imaging systems. Another application is as a terahertz radiation source as it is a strong photo-Dember emitter.

État de la surface et d'autres spécifications
Indium Antimonide wafer can be offered as wafers with as-cut, etched or polished finishes with wide range of doping concentration and thickness. The InSb wafer could be high quality epi-ready finishing.

Orientation Spécification

Indium antimonide surface orientations are supplied to an accuracy of +/- 0.5 degrees using a triple axis X-Ray diffractometer system. Indium antimonide substrates can also be supplied with very precise misorientations in any direction from the growth plane. The available InSb wafer orientation could be (100),(111), (110) or other orientation or mis degree.

Condition d'emballage

Polished wafer: individually sealed in two outer bags in inert atmosphere. Cassette shipments are available if required.
As-cut Wafer: Cassette shipment. (Glassine bag available on request).

Indium Antimonide Properties and Uses

The indium antimonide crystal structure is silver, brittle, and zinc blende structure. The indium antimonide lattice constant is 6.48 Å, and indium antimonide is a direct bandgap material with a narrow band gap of 0.18 eV. The indium antimonide conduction electron mobility is as high as 7800 cm2/V·s , which can be used to make infrared detectors, photomagnetic detectors and Hall devices.
