WebMar 28, 2024 · N-type Semiconductor Example. An intrinsic semiconductor material like Silicon (Si) has 14 electrons with a configuration of 2,8,4 and Germanium (Ge) has 32 electrons with a configuration of 2,8,18,4. Each atom requires 8 electrons in its valence shell to be stable. Hence intrinsic semiconductor atoms have covalent bonds based on … WebEventually, the mid-gap energy level Ei becomes smaller than the Fermi level EFP on the surface, which means that the substrate semiconductor in this region becomes n-type.
