Engineering Research Equipment Grant: Scanning Tunnelling Microscopy

用于超高真空的扫描隧道显微镜正在建造中。这将与已经购买的设备相结合，以提供一个超高真空系统，该系统包括扫描隧道显微镜、俄歇光谱、质谱仪、高分辨率电子能量损失光谱和样品制备能力。该系统将用于研究由铜和硅(用于合成甲基氯硅烷)形成的表面的结构；钨在硅上的化学气相沉积；铝、镍和铁表面氧化的初始阶段；以及金属衬底上金属单层的结构、生长机制和热稳定性。

A scanning tunnelling microscope for use in ultrahigh vacuum is being constructed. This will be combined with equipment already purchased to provide an ultrahigh vacuum system that contains scanning tunnelling microscopy, Auger spectroscopy, mass spectrometry, high-resolution electron energy loss spectroscopy, and sample preparation capability. The system will be used to study the structures of surfaces formed from copper and silicon (used for the synthesis of methylchlorosilanes); the chemical vapor deposition of tungsten onto silicon; initial stages of the surface oxidation of aluminum, nickel, and iron; and the structures, growth mechanisms, and thermal stabilities of metal monolayers on metal substrates.
