electron work function, Φ

https://doi.org/10.1351/goldbook.E02015
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: Math input error where Ve is the potential energy for electrons in metals and εeF is the kinetic energy of electrons at the Fermi level.
