Editing Work function (section)

== Work functions of elements ==
The work function depends on the configurations of atoms at the surface of the material. For example, on polycrystalline silver the work function is 4.26 eV, but on silver crystals it varies for different crystal faces as [[Miller index|(100) face]]: 4.64 eV, [[Miller index|(110) face]]: 4.52 eV, [[Miller index|(111) face]]: 4.74 eV.<ref>{{Cite journal | last1 = Dweydari | first1 = A.
