How are n type materials created
Web25 de nov. de 2024 · A p-type semiconductor is a semiconductor doped with atoms with three valence electrons which forms a covalent bond with the semiconductor and leaves behind a hole. In a p-type semiconductor, the electrons move in the process of occupying the holes. This movement of electrons constitutes the current flow. WebThe opposite effect, called recombination, occurs when an electron falls into a hole in the valence band. Because there are many more electrons than holes in n-type material, …
