利用低温非接触原子力显微镜(LT-NC-AFM)在5 K下观察了Si(100)表面的原子分辨率图像。Si(100)表面除了缺陷附近的对称二聚体结构外,几乎都是非对称二聚体结构。不对称二聚体主要为c(4×2)反平行锯齿型结构,部分为p(2×2)平行锯齿型结构。
We observed atomic resolution images of the Si(100) surface at 5K using low-temperature noncontact atomic force microscope (LT-NC-AFM). Si(100) surface shows almost the asymmetric dimers structure, except for the symmetric dimers structure near the defects. The asymmetric dimers are mainly c(4×2) structure with antiparallel zigzag pattern and partly p(2×2) structure with parallel zigzag pattern.
