P-Channel E-MOSFET
This type of MOSFET is called as p-channel MOSFET because the flow of current takes place by conduction of positive charge carriers, i.e., holes.
Construction of P-Channel E-MOSFET
A p-channel E-MOSFET consists mainly of three terminals: Source(S), Gate(G) and Drain(D). A substrate (SS) is made up of a n-type semiconductor and is internally connected with source terminal or sometimes brought out in a form fourth terminal. The other three terminals, i.e., drain, gate and source as connected to each other by p-doped region through metallic contacts. The figure given below shows the construction of p-channel E-MOSFET:

Enhancement MOSFET which is commonly called as E-MOSFET is a type of field effect transistor which is used mainly in voltage-controlled devices. It is a unipolar device, i.e. device in which conduction of current takes place either by electrons or holes. It is a three-terminal device which is mainly used as amplifier or in switching devices.
This type of transistor can be used both in analog and digital devices. These transistors are more popular than Bipolar junction transistors due to less power dissipation and negligible leakage current. These are smaller in size and hence find its application in integrated circuits (ICs).
