CAREER: Computational Approaches to Modeling Mechanical Phenomena at Nanoscales

在这个职业计划中，我们建议使用计算方法，将原子模拟工具与中尺度方法结合起来，来解决与纳米技术相关的问题。在晶体表面和半导体异质结构中的位错-障碍物相互作用的相互作用和动力学建模方面的拟议工作将为邻近表面上的纳米结构制造、纳米结构中的应力测量和弛豫外延外延生长等领域的实验工作提供指导。职业计划的教育部分旨在开发促进学科间信息转移的课程。具体来说，我们建议提供机会，本科研究项目nanoscience和开发高级/研究生coursesthat专注于建模的力学现象onnanoscales。课程将结合现代统计力学的方法和模型，重点是它们在纳米结构缺陷力学中的应用。

Abstact:In this career plan we propose to use computational approaches thatintegrate atomistic simulation tools with mesoscale methodologies totackle problems relevant to nanotechnology. The proposedwork on modeling of interactions and dynamics ofsteps on crystal surfaces and dislocation-obstacle interactionin semiconductor heterostructures will provide guidance to experimental work in the areas of nanostructure fabrication on vicinal surfaces, stress measurements innanoscale structures and growth of relaxed epitaxial semiconductorthin films.The educational part of the career plan aims atdeveloping curricula that fosters transfer of informationamong disciplines. Specifically, we propose to provide opportunities for undergraduate research projectsin nanoscience and to develop senior-level/graduate coursesthat focus on modeling of mechanical phenomena onnanoscales. The courses will incorporate methods and models ofmodern statistical mechanics with emphasis on their application to defect mechanics in nanostructures.
