Research Areas

Research Interests

Our current foci are collaborating with other research groups currently emphasizing mechanical behavior of small volumes such as spheres, bending beams, nanopillars and thin films undergoing failure. Materials of interest have included nanospheres of silicon and Ti; Si, NiAl and Fe-3wt%Si single crystals; PS/PMMA, DLC/MgO, and Cu/Si thin films. We have recently started initiatives with which to better understand the integrity of materials. One is real-time imaging of nanomechanical and micromechanical processes with AFM, TEM, and FEG-SEM (field emission gun scanning electron microscopy). An example of this is in situ fracture of silicon nanospheres and nanopillars. Such a nanoindentation instrument is in our newest TEM (Tecnai). A second example is nanoindentation induced dislocation emission in ceramic and metallic single crystals, thin films, and fracture of nano-beams in bending using in-situ scanning and ex-situ transmission electron microscopy. Surfaces and nanopillars undergoing nanoindentation or compression can be imaged by AFM and TEM directly before and after revealing nanometer scale physical properties as well.
