When a physical contact between a p-region & n-region is established which of the following is most likely to take place?

When a physical contact between a p-region and n-region is established, the most likely occurrence is the formation of a p-n junction. This process leads to the diffusion of charge carriers: electrons from the n-region will diffuse into the p-region, while holes from the p-region will diffuse into the n-region. This movement of charge carriers results in the creation of a depletion region at the junction, where an electric field is established due to the ionized donor and acceptor atoms. Ultimately, this forms the basis for many semiconductor devices, such as diodes and transistors.
