The purpose of this proposal is to finance a combined scanning tunneling and atomic force microscope which will allow to study the static and dynamic properties of atomic and molecular structures on surfaces at temperatures down to 300 mK and in a vector magnetic field of up to 9 T. In addition to determining the fundamental electronic, magnetic and mechanical properties of self-organized structures, the instrument will also be able to build, manipulate, and address artificial structures at the atomic level. The main research area of the instrument will be the investigation of spin phenomena, highly correlated states, and quantum effects on single and coupled magnetic atoms and molecules. In particular this instrument will be used for time-resolved electrical pump probe measurements as well as for the development of quantum-mechanically phase-coherent addressing methods by coupling microwaves into the tunnel junction.

该提案的目的是资助一种扫描隧道和原子力显微镜，该显微镜将允许在温度低至300 mK和矢量磁场高达9 T的条件下研究表面上原子和分子结构的静态和动态特性。除了确定自组织结构的基本电子，磁性和机械特性外，该仪器还能够在原子水平上构建，操纵和寻址人工结构。该仪器的主要研究领域将是研究自旋现象，高度相关的状态，以及对单个和耦合磁性原子和分子的量子效应。特别是，该仪器将用于时间分辨的电子泵探测测量，以及通过将微波耦合到隧道结中来开发量子力学相位相干寻址方法。
