Abstract

Abstact: In this career plan we propose to use computational approaches that integrate atomistic simulation tools with mesoscale methodologies to tackle problems relevant to nanotechnology. The proposed work on modeling of interactions and dynamics of steps on crystal surfaces and dislocation-obstacle interaction in semiconductor heterostructures will provide guidance to experimental work in the areas of nanostructure fabrication on vicinal surfaces, stress measurements in nanoscale structures and growth of relaxed epitaxial semiconductor thin films. The educational part of the career plan aims at developing curricula that fosters transfer of information among disciplines. Specifically, we propose to provide opportunities for undergraduate research projects in nanoscience and to develop senior-level/graduate courses that focus on modeling of mechanical phenomena on nanoscales. The courses will incorporate methods and models of modern statistical mechanics with emphasis on their application to defect mechanics in nanostructures.
