What is rectifying junction?

Answer 1

A rectifying junction is a type of semiconductor junction that allows current to flow primarily in one direction, functioning as a diode. This behavior is achieved by joining p-type and n-type semiconductor materials, creating a depletion region that forms a built-in electric field. When forward-biased, the junction allows current to pass, while reverse bias prevents current flow, thus rectifying the electrical current. Rectifying junctions are essential components in electronic devices, enabling controlled current flow and signal processing.
