The the channel, the better the device conducts. The charge carriers enter the channel at , and exit via the drain. MOSFET (metal-oxide semiconductor field-effect transistor, pronounced MAWS-feht) is a special type of field-effect transistor (FET) that works by electronically varying the width of a channel along which charge carriers (electrons or holes) . The width of the channel is controlled by the voltage on an electrode called the gate, which is located physically between and the drain and is insulated from the channel by an extremely thin layer of metal oxide., Manufacturer: Jnchdghwa
