Hall Effect
- Sep 04, 2018 -

Hall effect is a kind of magneto-electric effect, which was discovered by hall (a.h.all, 1855 -- 1938) when he studied the conductive mechanism of metal in 1879. Later, it was found that semiconductor, conductive fluid and so on also have this effect, and the hall effect of semiconductor is much stronger than that of metal. Various hall elements made by using this phenomenon are widely used in industrial automation technology, detection technology and information processing. Hall effect is a basic method to study the properties of semiconductor materials. The hall coefficient measured by hall effect experiment can be used to determine the important parameters such as the conductive type, carrier concentration and carrier mobility of semiconductor materials.
