Abstract

A technique for reducing the work function of a field-emission graphite cathode by doping it by an alkaline-earth metal (barium) is suggested. A model of formation of a barium monolayer on the cathode surface is proposed. Field-emission tests show that the operating voltage of the doped cathode is lower than that of the undoped one with the same emission current. (C) 2004 MAIK "Nauka / Interperiodica".
