摘要

研究了金属镱纳米膜单晶硅衬底类型界面产生的电荷密度驻波(弗里德尔振荡)对镱纳米层功函数的影响。结果表明，在0 ~ 8单原子层纳米膜厚度范围内，功函数具有振荡特性。这种功函数依赖于纳米膜厚度的特性是由于驻波非单调地改变了存在于金属表面的双电层的功率(动量)，从而影响了金属的功函数。这最终决定了功函数依赖于纳米膜厚度的振荡性质。关键词:表面，纳米膜，功函数，弗里德尔振荡，双电层，镱。

Effect of Friedel Oscillations on the Work Function of Ytterbium Nanofilms

The effect of standing waves of charge density (Friedel oscillations) generated by an interface of the metallic ytterbium nanofilm single-crystal silicon substrate type on the work function of ytterbium nanolayers has been studied. It is shown that in the range of nanofilm thicknesses from 0 to 8 monatomic layers, the work function has an oscillating character. This feature of the dependence of the work function on the nanofilm thickness is a consequence of the fact that the standing waves change nonmonotonically the power (momentum) of the electric double layer, which exists on the metal surface and affects the work function of the metal. This ultimately determines the oscillating nature of the dependence of the work function on the thickness of the nanofilms. Keywords: surface, nanofilm, work function, Friedel oscillations, electric double layer, ytterbium.
