本文给出了几种在硅（001）衬底上生长的稀土金属硅化物的扫描隧道显微镜图像。对于某些研究的金属（Dy，Ho），晶格匹配的各向异性与基板的结果在纳米线的形成。这些纳米线具有期望的性质，例如纳米横向尺寸、具有低缺陷密度的晶体结构和微米尺度长度。纳米线上的隧道光谱表明它们是金属的。
This paper presents scanning tunneling microscope images of several rare-earth metal silicides grown on silicon (001). For certain of the metals studied (Dy, Ho), an anisotropy in lattice match with the substrate results in the formation of nanowires. These nanowires have desirable properties such as nanometer lateral dimension, crystalline structure with a low density of defects, and micrometer scale length. Tunneling spectroscopy on the nanowires indicates that they are metallic.
