Semiconductor Physics

The three types of electronic materials are metals, semiconductors, and insulators. Metals have a high electrical conductivity, semiconductors have moderate conductivity, and insulators have very low conductivity.

The Fermi level is the energy level at which the probability of finding an electron is 0.5. It is important in semiconductors because it determines the electrical properties and behavior of the material.

Band-gap engineering refers to the manipulation of the energy band gap in semiconductors. This can be achieved through various techniques to control the electrical and optical properties of the material.
