MOSFET Device Physics and Operation

1 MOSFET Device Physics and Operation 1.1 INTRODUCTION A field effect transistor (FET) operates as a conducting semiconductor channel with two ohmic contacts – the source and the drain – where the number of charge carriers in the channel is controlled by a third contact – the gate.In the vertical direction, the gate-
