Abstract
A test that allows one to determine the compliance of the experimental data with the classical (orthodox) field dependence is described. The test is presented in two versions: using the Elinson–Schrednik approximation of the current–voltage characteristics in the classical Fowler–Nordheim coordinates, as well as the modern Forbes–Deane approximation with modified Murphy–Good coordinates. The use of the test is demonstrated by the study of a multitip emitter based on carbon nanotubes. A technique of online (real-time) calculation of the effective parameters of the emitter and testing is presented.
