The 'Average' Work Function and Emission Area in the Fowler-Nordheim Equation.

Original language description

Derivation of the elementary Fowler-Nordheim equation is based on several strong physical assumptions (e.g. smooth fiat surface and uniform work function across emitting surface, constant emission area and a uniform distribution of the applied field overit). A real emitter, however does not fulfill these assumptions. In spite of it the total emission current follows the FN equation and is frequently used for an estimation of the 'average' work-function. The physical basis of this procedure and of terms'averageů work function and 'emission area' are analyzed from the experimentalist''s point of view. Thus some of the older - more or less intuitive - conclusions are substantiated.
