ENGINEERING RESEARCH EQUIPMENT: Surface Analysis Equipment for High-speed Variable-Temperature Ultrahigh-Vacuum Scanning Tunnelling Microscopy

购买了将安装在现有超高真空系统中的9411568台奥特曼设备。这包括一个用于俄歇电子光谱和低能离子散射光谱的双程柱面反射镜分析器，一个低能电子衍射系统，以及一个用于热解吸的四极质谱计。该设备将与高速、变温、扫描隧道显微镜(STM)一起使用，以研究表面过程的动力学。使用该设备的项目包括研究金属表面的刻蚀反应，对氧化物表面特定位置的吸附、脱附和反应速率的动力学测量，以及研究金属薄膜成核和生长过程中的表面混合。***

9411568 Altman Equipment to be installed in an existing ultrahigh-vacuum system is acquired. This includes a double-pass cylindrical mirror analyzer for Auger electron spectroscopy and low-energy ion-scattering spectroscopy, a low-energy electron diffraction system, and a quadrupole mass spectrometer for thermal desorption. This equipment is to be used with a high-speed, variable-temperature, scanning tunnelling microscope (STM) to study the dynamics of processes at surfaces. Projects using this equipment include studies of etching reactions at metal surfaces, kinetic measurements of adsorption, desorption, and reaction rates at specific sites on oxide surfaces, and studies of surface intermixing during nucleation and growth of thin metal films. ***
