中文简介: | 通过操纵表面单个原子和分子可以实现新的量子结构。最近将介绍通过低温超高真空扫描隧道显微镜操纵这些基本建筑物种的工作,结合各种隧道光谱方法。所进行的实验对于新型纳米器件的基本理解和构造都是重要的。描述将是i.a.测量移动单个原子所需的横向力,实现多步骤单分子开关,以及由原子和分子组成的混合装置。 |
课程简介: | Novel quantum structures can be realized by manipulating surface single atoms and molecules. Recent efforts in manipulating these basic construction species by means of a low-temperature ultra high vacuum scanning tunneling microscope, combined with a variety of tunneling spectroscopic methods, will be presented. The performed experiments are important for both, fundamental understanding and construction of novel nano-devices. Described will be i.a. measurements of lateral forces required to move individual atoms, realization of a multi-step single molecule switch, and an hybrid device, composed of atoms and molecules. |
