Zink is supported by the Experimental Physical Chemistry Program to continue his studies of excited electronic states and reactivity of inorganic molecular precursors for photodeposition of metals and semiconductors. The project has three complementary objectives: to characterize spectroscopically the excited electronic states of metal containing compounds, to study their single and multiphoton photochemistry and correlate it with the spectroscopy, and to make nanostructures of metals and semiconductors by photochemical reactions of these compounds. Outcomes from this project will be a thorough spectroscopic understanding of the excited electronic states of these inorganic compounds, interpretation of the photochemical reactions from these states, and insights into the photochemical conditions necessary to deposit nanostructured materials controllably. Thin film materials have important technological applications, and improvements in the fabrication of multilayer structures with well-defined physical properties are sought to increase the capabilities of semiconductor manufacturing. Real-time chemical information about activated gas phase species involved in materials growth on surfaces will enhance the understanding of chemical vapor deposition used for industrial processing.

Zink得到实验物理化学计划的支持，继续研究金属和半导体光沉积的无机分子前体的激发电子态和反应性。该项目有三个互补的目标：光谱表征含金属化合物的激发电子态，研究其单光子和多光子光化学并将其与光谱相关联，以及通过这些化合物的光化学反应制造金属和半导体的纳米结构。 该项目的成果将是对这些无机化合物的激发电子态的彻底光谱理解，对这些状态的光化学反应的解释，以及对可控存款纳米结构材料所需的光化学条件的深入了解。薄膜材料具有重要的技术应用，并且寻求在具有良好限定的物理性质的多层结构的制造中的改进以增加半导体制造的能力。 实时化学信息的活化气相物种参与材料生长的表面将提高化学气相沉积用于工业加工的理解。
