  • An effective binding energy and a formula f or evaporation fields in tlie configu-ration of a scarming tunneling microscope has been introduced. Based on which, evaporation fields for various tip/substrate combinations, especially those for non-identical tip/substrate combinations have been calculated. To do this a universal function for atomic potential of an adatom at different distances from a metai surface is proposed.
