An infrared detector is a device that is used to detect and measure infrared radiation, which lies beyond the visible spectrum of light. These detectors are utilized in various applications,...

intrinsic photoconductivity

The absorption of a photon raising an electron across the forbidden gap from valence to conduction band of the semiconductor where conductivity is increased and incident radiation may be measured.

N-type conductivity

In a semiconductor, the state created by the addition of a dopant that provides excess electrons.

P-type conductivity

In a semiconductor, the state created by the addition of a dopant that creates excess holes.
