electron work function, Φ

The minimum work needed to extract electrons from the Fermi level of a metal M across a surface carrying no net charge. It is equal to the sum of the potential energy and the kinetic Fermi energy taken with the reverse sign:
Φ M = − ( V e + ɛ e F )
whera V e is the potential energy for electrons in metals and ɛ e F is the kinetic energy of electrons at the Fermi level.
