Вольт-амперная характеристика термоионной эмиссии Na с поверхности Na-=SUB=-x-=/SUB=-Au

Abstract

In a high-vacuum diode, the volt-ampere characteristic of the thermionic emission of Na+ with surface of NaxAu intermetallide. Its hysteresis was found, which is associated with changes in the surface NaxAu caused by the action of an external electric field. In accordance with the Schottky effect, analysis of the current–voltage characteristic and the value of the work function of the NaxAu surface was estimated. Suggested mechanism of thermionic emission of Na+ from the surface of NaxAu.
