Research Areas

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.

Open Positions

Master Thesis

  • In situ tensile testing of twinned Au nanowires

    Quantitative mechanical testing is performed inside a scanning electron microscope, and the stress- strain behavior of the wires is determined.

Bachelor Thesis

  • Characterization of twinned and untwinned Au nanowires

    Au nanowires are characterized in a transmission electron microscope. The influence of a longitudinal twin boundary on shape, rigidity, aspect ratio, and cross section is evaluated.
