Concept of field Emission:-

Electric field electron emission is the process by which free electrons are emitted from the metal surface when strong electric field is applied. Electric field electron emission is also called as electron field emission, field electron emission and field emission. Electric field electron emission occurs not only in metals, but also in liquids. Field electron emission occurs in metals that are placed at very strong electric field. In other words, field electron emission occurs when large amount of energy in the form of electric field is applied to the free electrons in the metals.
