The conventional theory of field emission from metals consists of the Fowler-Nordheim tunneling analysis with space-charge effects accounted for using the «image-force» concept. This one-electron approach is highly questionable because the potential barrier through which the tunneling occurs is located very close (<3 A) to the cathode interface, a region in which the charge density is quite high due to «spillover» effects. In this paper, we give an improved analysis of the field-emission… CONTINUE READING
