WebA P-N junction is formed when a p-type semiconductor and an n-type semiconductor are placed in contact with each other. Current flows readily in one direction through this junction (this direction is referred to as forward biased), but will not flow easily in the opposite direction (which is reverse biased). WebA p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains …
