Mechanical stress can impose huge free energy changes in materials, thereby altering both the equilibrium states and the dynamic behavior. Particularly in nanoscale materials where the defects are constrained by interfaces and surfaces, very large stresses are reached and dynamic processes such as deformation and phase transformations may follow entirely different paths than in bulk materials. We investigate a variety of different nanoscale model systems using in-situ electron microscopy and micro-mechanical testing, with the goal of revealing the underlying principles controlling material stability, defect dynamics, and energy dissipation. Details of the ongoing Projects can be found on our Homepage.
