The formation of surface Li-Sb alloy and its electronic structures are investigated with x-ray photoelectron spectroscopy (XPS). From the information on core-level shift of Sb 3d and Li 1s XPS spectra, the presence of charge transfer from Li to Sb is confirmed, while the chemical composition of formed alloy is estimated as Li(3)Sb. The density of states from valence band XPS shows a significant nonrigid part of band structures, suggesting strong covalent bonding between Li and Sb.
利用X射线光电子能谱（XPS）研究了表面Li-Sb合金的形成及其电子结构。根据Sb 3d和Li 1s XPS光谱的芯能级位移信息，证实了从Li到Sb的电荷转移，同时估计形成的合金的化学组成为Li(3)Sb。价带XPS的态密度显示出能带结构中显著的非刚性部分，表明Li和Sb之间存在强共价键。
