摘要
本工作利用热能碱金属原子与炽热W,Pt表面的相互作用,研究了碱金属原子与金属表面的电荷交换,以及金属表面吸附原子后表面功函数的变化。
The interaction of thermal alkali atoms on hot tungsten and platinum filaments has been studied experimentally. The positive ion current has been measured as a function of the surface temperature. Electron exchange between the adatom and metal surface and the change of work function of the adsorbed metal surface have been discussed.
