A PIN diode is a diode with a wide, ... Some detectors can use avalanche multiplication. The same mechanism applies to the PIN structure, or p-i-n junction, ...
A 2-D tetra-lateral PSD is capable of providing continuous position measurement of the incident light spot in 2-D. It consists of a single square PIN diode with a resistive layer. When there is an incident light on the active area of the sensor, photocurrents are generated and collected from four electrodes placed along each side of the square ...
They are also widely used in various medical applications, such as detectors for computed tomography (coupled with scintillators), instruments to analyze samples (immunoassay), and pulse oximeters. PIN diodes are much faster and more sensitive than p–n junction diodes, and hence are often used for optical communications and in lighting ...

A PIN diode has a central un-doped, or intrinsic, layer, forming a p-type/intrinsic/n-type structure. [42] They are used as radio frequency switches and attenuators. They are also used as large-volume, ionizing-radiation detectors and as photodetectors. PIN diodes are also used in power electronics, as
Liulin-type is a class of spectrometry-dosimetry instruments. [1] The instruments are specific types of semiconductor-based ionizing radiation sensors that are capable of measuring the deposited energy of the particle in silicon PIN diode and also the flux of particles.
Detectivity: The square root of the detector area divided by the noise equivalent power. Gain: The output current of a photodetector divided by the current directly produced by the photons incident on the detectors, i.e., the built-in current gain. Dark current: The current flowing through a photodetector even in the absence of light.
The structure of the silicon APD. An avalanche photodiode (APD) is a highly sensitive type of photodiode, which in general are semiconductor diodes that convert light into electricity via interband excitation coupled with impact ionization.
