Generalized semiconductor junction
In solid-state physics, a metal–semiconductor (M–S) junction is a type of electrical junction in which a metal comes in close contact with a semiconductor material. It is the oldest practical semiconductor device. M–S junctions can either be rectifying or non-rectifying. The rectifying metal–semiconductor junction forms a Schottky barrier, making a device known as a Schottky diode, while the non-rectifying junction is called an ohmic contact. (In contrast, a rectifying sem… WebFrom the lesson. Schottky diodes. In this module, you will learn about the simplest semiconductor device, a Schottky diode, which consists of a metal-semiconductor junction. You will apply the drift-diffusion model, solving Gauss' law leading to the depletion layer width, the maximum electric field and capacitance versus voltage relation.
