Abstract

The electronic structure of a gold film deposited on W was studied during the adsorption of sodium atoms. An analysis of the photoemission spectra from the valence band and core levels of Au 4f and Na 2p upon synchrotron excitation in the photon energy range of 80–600 eV showed that Na adsorption leads to the formation of Na_xAu_y intermetallic compounds of various stoichiometry under the Na monolayer.

钠原子吸附对金薄膜电子结构的影响

摘要研究了沉积在 W 上的金薄膜在吸附钠原子时的电子结构。在 80-600 eV 的光子能量范围内，通过分析同步辐射激发下 Au 4f 和 Na 2p 的价带和核级的光发射光谱，发现 Na 的吸附导致在 Na 单层下形成了不同化学计量的 NaxAuy 金属间化合物。
