electron voltage (eV)

Electron volt (eV) is a unit for small energies. It is the energy possessed by an electron when it is accelerated by one volt. One electron volt is equal to the energy of 1.6021764x10exp-19 joules

(J).

Bandgaps of various sem

iconductors The electron volt is mainly used for semiconductors and compound semiconductors and describes the energy required to overcome the bandgap. Depending on the semiconductor, this can be less than 1 eV, but can also be several electron volts. For example, the band gap of silicon (Si) is 1.1 eV, that of gallium nitride (GaN) 3.4 eV.
