Development of Scanning Tunneling Spectroscopy (STS) for Research in Mineralogy and Geochemistry

这项资助提供了109,205美元，用于资助一个为期两年的博士后职位和必要的设备，以开发扫描隧道光谱（STS）方法，用于研究在超高真空（UHV）下暴露于O2和H2O的矿物表面。该研究对阐明许多与低温环境地球化学有关的矿物的原子级电子结构和反应性具有很大的潜力。这项工作将使用现有的扫描隧道显微镜（STM）完成，并将包括制定标准化程序，以制备用于STS分析的矿物表面，制备用于状态密度平坦化的STS尖端，以及收集数据的方法。＊＊＊

9527092 Hochella This grant provides $109,205 in support of the costs of funding a two-year postdoctoral position and necessary equipment to develop scanning tunneling spectroscopy (STS) methods for interrogating mineral surfaces exposed to O2 and H2O under ultra-high vacuum (UHV). This research has great potential to elucidate the atomic-level electronic structure and reactivity of many minerals of relevance to low temperature environmental geochemistry. The work will be done using an existing Scanning Tunneling Microscope (STM) and will include the development of standardized procedures for preparing mineral surfaces for STS analyses, preparation of STS tips for density-of-state-flattening and methods of data collection. ***
