Semiconductor diodes can be defined as diodes that are made up of semiconducting materials (typically, the metals silicon and germanium are used in them). ... The junction between the cathode and the anode in a semiconductor diode features the formation of a depletion region, which does not contain electrons or holes.

What is the semiconductor diode used?

Semiconductor diode as a rectifier: Diodes are generally used to convert Alternating current to direct current. Semiconductor diode in clamping circuit: These are used to switch over to a positive from a negative input signal or vice versa.

What are examples of semiconductor?

Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others.
