Abstract:

In this work, we develop order parameters to detect the structural changes that occur as Au nanowires are mechanically deformed. These order parameters are developed in the context of shape matching, allowing us to create highly specialized order parameters within a single, general framework. We use these order parameters to quantify the rate and temperature- dependent behavior of mechanically deformed nanowires. The results of our structural analysis quantify and confirm the recently discovered rate-dependent energy release mechanism that dictates the relaxation modes of the nanowires.
