Dark current definition
WebDefinition of Photodiode It is a semiconductor device having 2 terminals that produce current when exposed to light. Photodiode works on the principle of photoelectric effect thus convert light energy that falls on the surface of the material into electrical energy. As the intensity of incident radiation increases, the current through the device also increases. WebThe dark current is generated when the holes or the electrons get excited thermally across the path of the current. These are the comparatively smaller flow of electric …

WebDark-current spectroscopy can be used to determine the defects present by monitoring the peaks in the dark current histogram's evolution with temperature. Webdark current: [noun] the current through a photoelectric or photoconductive cell when an electromotive force is applied in the absence of light.
WebMar 16, 2024 · I found this definition of collector dark current on a website: "When the phototransistor is placed in the dark and a voltage is applied from collector to emitter, a certain amount of current will flow. This current is called the dark current (ID). This current consists of the leakage current of the collector-base junction multiplied by the dc ...
