Nucleation, Growth, and Structure of Metal-on-Metal Films

9317660埃文斯这个奖项，由分析和表面化学计划，提供了一个合作研究项目，涉及教授泰尔和埃文斯在爱荷华州州立大学的支持。 在为期三年的持续资助期间，PI将使用理论和实验的明确结合来研究金属对金属薄膜中的非平衡结构。 Thiel教授将探索由于边缘扩散、岛屿溶解或岛屿逃逸的有限速率而形成的非平衡结构。 埃文斯教授将进行非平衡实验系统的复杂理论建模。化学家和数学家之间的这种独特的合作将允许在岛结构的成核和生长过程中对尺寸和密度分布进行实验和理论分析。 实验方法包括扫描隧道显微镜和低能电子衍射。 教授泰尔和埃文斯将研究固体表面上的薄膜生长的实验和理论方面。 拟议研究的目的是提高我们对薄膜生长的理解，以及控制这些技术重要系统的机制和生长速率的化学因素。 ***

9317660 Evans This award, made by the Analytical and Surface Chemistry Program, provides support for a collaborative research project involving Professors Thiel and Evans at Iowa State University. During the tenure of this three-year continuing grant, the PIs will investigate nonequilibrium structure in metal-on-metal films using a well-defined combination of theory and experiment. Professor Thiel will explore nonequilibrium structures which are formed due to limited rates of edge diffusion, island dissolution, or escape from islands. Professor Evans will carry out the complex theoretical modeling of the nonequilibrium experimental systems. This unique collaboration between a chemist and mathematician will allow combined experimental and theoretical analyses of size and density distributions during nucleation and growth of island structures. The experimental methods to be used include scanning tunneling microscopy and low-energy-electron diffraction. %%% Professors Thiel and Evans will investigate the experimental and theoretical aspects of film growth on solid surfaces. The objective of the proposed research is to enhance our understanding of the growth of thin films and the chemical factors that control the mechanisms and rates of growth of these technologically important systems. ***
