Preferred Label : electron work function;
Detailed label : electron work function, Φ;
IUPAC definition : 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: \[\mathit{\Phi} {M} -(V_{{e}}
ɛ_{{e}} {F})\] where V e is the potential energy for electrons in metals and ɛe F
is the kinetic energy of electrons at the Fermi level.;
