A semiconductor detector in ionizing radiation detection physics is a device that uses a semiconductor (usually silicon or germanium) to measure the effect of incident charged particles or photons. Semiconductor detectors find broad application for radiation protection , gamma and X-ray spectrometry , and as particle detectors .
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators.
SPADs are semiconductor devices that are based on a p–n junction that is reverse-biased at an operating voltage that exceeds the junction's breakdown voltage (). [3] " At this bias, the electric field is so high [higher than 3×10 5 V/cm] that a single charge carrier injected into the depletion layer can trigger a self-sustaining avalanche.
Based on device structure, photodetectors can be classified into the following categories: MSM Photodetector: A metal-semiconductor-metal (MSM) photodetector consists of a semiconductor layer sandwiched between two metal electrodes. The metal electrodes are interdigitated, forming a series of alternating fingers or grids.
Keithley Instruments Series 4200 CVU. Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results.
Surface photovoltage (SPV) measurements are a widely used method to determine the minority carrier diffusion length of semiconductors.Since the transport of minority carriers determines the behavior of the p-n junctions that are ubiquitous in semiconductor devices, surface photovoltage data can be very helpful in understanding their performance.
A semiconductor device that produces coherent laser radiation when properly energized. leakage inductance The inductance of a transformer that results from magnetic flux not linked by both primary and secondary windings. light-emitting diode A semiconductor device that produces light or infrared or ultraviolet radiation when properly energized.
Semiconductor devices like the crystal detector work by quantum mechanical principles; their operation cannot be explained by classical physics. The birth of quantum mechanics in the 1920s was the necessary foundation for the development of semiconductor physics in the 1930s, during which physicists arrived at an understanding of how the ...
