利用亚稳原子电子能谱（MAES）和角分辨紫外光电子能谱（ARUPS），结合有机体系的强度分析，研究了端氢Si(111) [H-Si (111)-(1×1)]的表面电子态。利用MAES选择性地观察了源自Si-H键的H-Si (111)-（1×1）的表面态，激发了分布在最外层表面的电子。此外，利用有机薄膜的简单计算模型对光电子角分布进行了定量分析，证实了在真空能级上具有非常小色散的ARUPS峰来源于非色散Si-H σ态。
The surface electronic states of hydrogen-terminated Si(111) [H–Si(111)-(1×1)] were studied by metastable atom electron spectroscopy (MAES) and angle-resolved ultraviolet photoelectron spectroscopy (ARUPS), coupled with an intensity analysis used for organic systems. The surface states of H–Si(111)-(1×1) originated from Si–H bonds were selectively observed by MAES which can excite electrons distributed at the outermost surface. Furthermore, the prominent ARUPS peak with very small dispersion at around 10 eV binding energy from the vacuum level was confirmed to originate from a nondispersive Si–H σ state by quantitative analysis of the photoelectron angular distribution using a simple computation model used for organic thin films.
