论文摘要

我们介绍了SI(111) - (7x7)表面上的Rubidium吸附的研究以及相关的RB诱导的重建,这是通过扫描隧道显微镜(STM)(STM)和低能量电子衍射(LEED)(LEED)通过扫描隧道显微镜(STM)(STM)通过扫描隧道显微镜(STM)和RB覆盖的函数的函数。通过LEED的样本分析可以首次观察RB/SI(111) - (6x1)重建。 STM图像分析允许获得RB/SI(111) - (3x1)表面的第一个真实空间表征。此外,STM提供了有关表面布置的直接和局部信息,以及有关SI和RB原子以及生长动力学之间相互作用的进一步见解。

We present a study of the rubidium adsorption on the Si(111)-(7x7) surface and the related Rb-induced reconstructions as a function of deposition temperature and Rb-coverage via scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED). Sample analysis via LEED allowed to observe for the first time a Rb/Si(111)-(6x1) reconstruction. The STM image analysis allowed to obtain the first real space characterization of the Rb/Si(111)-(3x1) surface. In addition, STM provided a direct and local information on the surface arrangement as well as further insights on the interaction between Si and Rb atoms and on the growth dynamics.
