Description

Nanomechanical properties are critical for the design of all nanodevices. For example, all nanodevices experience mechanical loads during processing and service, and quantitative predictions of failure strengths are needed to ensure reliability and maximize performance. We use numerous modeling approaches to explore the mechanical and electrical behavior of deforming nanoscale systems. Current examples include using finite element and classical atomistic modeling to study nanoindentation, and using density functional theory and semiempirical tight binding to study the deformation, band structure, and electron transport of Au nanowires. All of our modeling activities have a major advantage of being directly associated with world-leading experimental efforts. In addition to making valuable contributions to the art of designing nanodevices, these quantitative studies provide valuable opportunities for basic research into material behavior and energetics at the nanoscale.
