Explanation: When p & n region come together diffusion takes places & a depletion
region is established with opposite charges on both the sides of the junction.
When a physical contact between a p-region and an n-region is established, the most likely occurrence is the formation of a p-n junction. At this junction, electrons from the n-region will diffuse into the p-region where there are holes, while holes from the p-region will diffuse into the n-region where there are excess electrons. This movement of charge carriers leads to the formation of a depletion region at the junction, which has an electric field that can create a potential barrier. This is a fundamental principle behind the operation of semiconductor devices such as diodes and transistors.
