Photovoltaic Indium Antimonide (InSb) Infrared Detectors
Supplier: Infrared Associates
Technology type: Infrared Photodetectors
InfraRed Associates, Inc. offers photovoltaic indium antimonide detectors (InSb), which are characterised by their high bandwidth. These InSb detectors offer excellent electro-optical performance and are designed for the wavelength range from 1 micron to 5.5 microns.
Principle
The photovoltaic effect is the generation of potential over the p-n transition when radiation of the correct wavelength hits it. When the photon flow irradiates the transition, electron-hole pairs are formed when the photon energy exceeds the bandgap.
The field brings electrons from the p-range to the n-range and the holes from the n-range to the p-range. This process makes the p-region positive and the n region negative and generates a current flow in an external circuit. An image of the InSb detector is displayed on the right. This consists of both a signal and noise current generator in parallel with a resistive and capacitive term.
With the detector, a suitable preamplifier can be offered, which is optimally adapted to the selected detector.
