What are Semiconductor Sensors?

Feb 13, 2019· Introduction to Semiconductor Sensors. A sensor detects an event or a change in a factor and responds with an output. The measured phenomenon may be chemical, electrical, mechanical, radiant, magnetic or thermal. The sensor picks up a signal and passes it to a modifier, the first part of the sensor…

Operating principle ‐MOStype gas sensor

Operating principle. When semiconductor particles (typically tin dioxide) are heated in air at high temperature, oxygen is adsorbed on the particle surface by capturing free electrons. The depletion layer thus formed is largely dependent on the radius of semiconductor particles used. If it is as small as conventionally used in gas sensors …
