Abstract
The recently developed general theory of electron emission from metals is extended to semiconductors assuming an arbitrary position of the Fermi level at the surface, and a parabolic energy‐momentum relation with an electron effective mass differing from the free electron mass. The expressions obtained for the emission current density from the conduction band are valid for all emission condition between the limits of thermionic and field emission. The formulae for the current originating from the valence band apply to wider emission conditions than those proposed in earlier work.Keywords
