Field Effect Transistor (FET) The field effect transistor is a three terminal unipolar solid state device in which voltage is controlled by an electric field . Source Types There are two types of FET -

Fermi Fermi Energy "The maximum energy occupied by an electron at 0°k is Fermi energy." Basically it's a concept in quantum mechanics .The energy of the highest level of quantum state is Fermi
