Current flows into the Drain (D), through the channel, and out of the Source (S) In the normal operation of an n-channel device, the Drain (D) is positive with respect to the Source (S).Major structure is n-type material (channel) between embedded p-type materialto form 2 p-n junction.FET is unipolar – uses only one type of current carrier.BJT is bipolar – conduction both hole and electron.
