摘要

摘要在高真空二极管中，Na+与 NaxAu 金属间化合物表面的热离子发射的伏安特性被发现。发现其滞后性与外部电场作用引起的 NaxAu 表面变化有关。根据肖特基效应，分析了 NaxAu 表面的电流-电压特性和功函数值。提出了 Na+ 从 NaxAu 表面热离子发射的机理。

Current–Voltage Characteristic of the Thermal Ion Emission of Na From the NaxAu Surface

Abstract

In a high-vacuum diode, the volt–ampere characteristic of the thermionic emission of Na⁺ with surface of Na_xAu intermetallide. Its hysteresis was found, which is associated with changes in the surface Na_xAu 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 Na_xAu surface was estimated. Suggested mechanism of thermionic emission of Na⁺ from the surface of Na_xAu.
