摘要
本文利用超高真空ＳＴＭ和ＬＥＥＤ装置观察了错切角为０．５°和４．５°的Ｓｉ（１００）微斜面的原子结构．观察到错切角为０．５°时ＳＴＭ像为单原子高度台阶表面结构，错切角为４．５°时ＳＴＭ像为双原子高度台阶结构．
Abstract The surface atomic structures are observed on St(100) vicinal surface for miscut angles of 0.5°and 4.5°by UHV-STM and LEED.The STM image is shown the surface structure of the single atomic height step for miscut angle of 0.5°,and the surface structure of the double atomic height step for miscut angle of 4.5°.
