提案编号：CMS-0547409提案标题：Career：薄膜中不断演变的表面图案的研究和教育主要研究员：瑞皇表演组织：德克萨斯大学奥斯汀分校摘要从基础和实践两个方面考虑，拟议的研究项目将开发基于物理的数学模型和高效的模拟方法，以了解薄膜材料中图案形成的动力学。具体地说，提出了两个研究任务：任务A将开发一个动力学模型来模拟软衬底上硬膜中褶皱图案的演化过程，任务B将开发一个数学上相似的模型来模拟量子点在异质外延系统中的自组装。其目的是对这两个系统中的模式演化动力学进行定量的了解，并探索新的工程技术来控制模式。这项拟议的研究将对技术应用设备的制造产生重大影响。拟议的教育活动包括课程开发、新的教育工具、本科生和来自代表性不足群体的学生的研究经验、针对K-12学生和教师以及普通公众的外联活动。

Proposal Number: CMS-0547409Proposal Title: CAREER: Research and Education on Evolving Surface Patterns in Thin FilmsPrincipal Investigator: Rui HuangPerforming Organization: University of Texas at AustinAbstractOf both fundamental and practical interest, the proposed research project will develop physics-based mathematical models and efficient simulation approaches to understand the dynamics of pattern formation in thin-film materials. Specifically, two research tasks are proposed: Task A will develop a kinetic model to simulate the evolution process of wrinkle patterns in hard films on soft substrates, and Task B will develop a mathematically similar model to simulate self-assembly of quantum dots in heteroepitaxial systems. The objective is to develop a quantitative understanding of the pattern evolution dynamics in both systems and to explore novel engineering techniques to control the patterns. The proposed research will have a significant impact on the making of devices for technological applications. The proposed education activities include curriculum development, new tools for education, research experience for undergraduates and students from underrepresented groups, outreach activities directed to K-12 students and teachers as well as the general public.
