Islands composed of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) molecules are grown on a hydrogen passivated Ge(001):H surface. The islands are studied with room temperature scanning tunneling microscopy and spectroscopy. The spontaneous and tip-induced formation of the top-most layer of the island is presented. Assistance of the scanning probe seems to be one of the factors that facilitate and speed the process of formation of the top-most layer.
由苝-3,4,9,10-四羧酸二酐 (PTCDA) 分子组成的岛屿生长在氢化的 Ge(001):H 表面上。使用室温扫描隧道显微镜和光谱法对这些岛屿进行了研究。本文展示了岛屿最顶层的自发和针尖诱导形成过程。扫描探针的辅助似乎是促进和加速最顶层形成过程的因素之一。
