Forbes, RG (2010) P2-31: Simple derivation of formula for sommerfeld supply density In: 23rd IVNC 2010, 2010-07-26 - 2010-07-30, Palo Alto, USA.

This poster presents a simple derivation of the result that (for a large free-electron conductor) the electron supply density is constant in energy-space and is given by the Sommerfeld supply density zS, and also proves the formula for zS. This result is the best starting point for deriving Richardson-Schottky-type and Fowler-Nordheim-type equations. For small emitters the supply density is not constant in energy-space; consequently, emission from small emitters is not well described by these equations.
