Applications

Where this wafer delivers value

01

MWIR Infrared Detection

With a narrow bandgap of approximately 0.17 eV at 300 K, InSb is ideal for MWIR detection in the 3–5 μm range. Typical applications include cooled infrared detectors, focal plane arrays (FPAs), thermal imaging, and gas sensing.

02

Magnetic Sensors

InSb wafer combines high electron mobility with strong magnetoresistive properties, making it suitable for sensitive magnetic sensing. Applications include Hall-effect sensors, magnetic field detectors, and position or current sensing devices.

03

Cryogenic & High-Mobility Electronics

InSb's narrow bandgap and exceptionally high electron mobility make it attractive for advanced semiconductor research. Applications include high-mobility transistors, cryogenic electronics, and low-temperature III–V device development.

FAQ

Common questions about this product

Quick answers on material selection, customization, testing and ordering.

InSb is widely used for MWIR detection in the approximately 3–5 μm atmospheric window, particularly in cooled infrared detector systems.

Both N-type and P-type InSb can be used depending on the detector architecture and epitaxial or device requirements.

N-type InSb is commonly selected for Hall sensors and other high-mobility magnetic sensing devices due to its exceptional electron mobility.
