9522240 Chiang This Nano 95 award is for the development of a unique, variable temperature UHV AFM/STM instrument which will allow unique control of the sample temperature from 4K to 400K. In addition, the instrument will be coupled to a surface analysis and preparation system for controlled sample conditions. New types of scientific problems will become accessible with such an instrument, including the adsorption of molecules on surfaces at low temperatures, the in situ observation of chemical reactions as a function of temperature the observation of surface transitions in both physisorbed and chemisorbed systems, the direct measurement of forces used to move atoms on surfaces, and the atomic scale mechanical properties of surfaces at low temperature. %%%

9522240这项纳米95奖是为了表彰一种独特的、变温的超高压原子力显微镜/扫描隧道显微镜仪器的开发，该仪器将允许独特地控制从4K到400K的样品温度。此外，该仪器还将与用于控制样品条件的表面分析和制备系统相连接。有了这种仪器，新的科学问题将成为可能，包括分子在低温下在表面上的吸附，作为温度函数的化学反应的现场观察，物理吸附和化学吸附系统中表面转变的观察，用于在表面上移动原子的力的直接测量，以及低温下表面的原子尺度机械性质。%%%
