What are semiconductor devices?

Semiconductor devices are electronic components that exploit the electrical properties of semiconductor materials like silicon and germanium. They are fundamental to modern electronics and include diodes, transistors, and integrated circuits.

What is a p-n junction diode?

A p-n junction diode is formed by joining a p-type semiconductor and an n-type semiconductor. It allows current to flow primarily in one direction: from the p-type to the n-type side when forward-biased.

A rectifier is an electrical component that converts alternating current (AC), which periodically reverses direction, into direct current (DC), which flows in only one direction. Half-wave and full-wave rectifiers are common types.

What happens when a p-n junction is reverse biased?

When a p-n junction is reverse-biased, a larger depletion layer forms, significantly impeding the flow of majority charge carriers and thus allowing only a very small leakage current to pass.

What is the significance of the depletion layer?

The depletion layer is a region in a semiconductor device, typically at the p-n junction, where mobile charge carriers (electrons and holes) have been swept away, leaving behind immobile ions. This layer creates a potential barrier that controls current flow.
