在Si(110)表面,当每个晶胞中掺入约8个金原子时,可以形成稳定的重构。通过扫描隧道显微镜,我们观察到一个阵列的一维链与内部双行结构。角分辨光电子能谱表明,这种重建形成了一个金属带,在费米能级分裂。
The Si(110) surface is found to form a stablereconstruction upon incorporation of about eight gold atoms perunit cell. By means of scanning-tunneling microscopy we observe an array of one-dimensional chains with an internal double-row structure. Angle-resolved photoemission reveals that this reconstruction forms a metallic band which is split at the Fermi level.
