Abstract

A sensitive method of testing the surface finish of a metal has been suggested based on the principle of field emission. The quasi-classical calculation of the field-emission current from a plane metal surface shows that the calculated current is always less than the experimental current. The discrepancy between these theoretical and experimental currents has been shown to be a measure of the nonplanarity of the metal surface from which one can get information about how much finish a particular metal surface can take.
