Schottky Effect
The Schottky effect is a reduction in the energy required to remove an electron from a solid surface in a vacuum that occurs by applying an electric field to the surface. It refers to an increase in the emission of electrons from the surface of a heated material due to the application of an electric field, which reduces the value of the energy required for electron discharge In other words, we can say in the presence of an electric field, the energy required to remove electrons from a surface in a vacuum is less. The applied field reduces the barrier height. As a result, there is an increase in electron discharge from the surface. This process is the Schottky effect. The energy required for an electron to escape the surface of a material is known as the work function. As the electric field increases, at a point at which the value of the work function itself lowers. With the increase of the field again, the work function continues to decrease, leading to an increase in elec
