Electron Microscopy

Innovative scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques are used to understand the micro-physical basis of Earth material properties.  We use: electron backscattered diffraction (EBSD) in the SEM to map the crystal orientations and textures of a range of materials including ice (cryo EBSD): cathodoluminescence to probe defect structures and chemistry of a wide range of microstructures: and fast ion beam (FIB) SEM tomography to study three dimensional pore-networks of fluids (water, oil and melts) in rocks at the nanoscale.  The FIB-SEM is also applied to studies of crystal growth of natural and synthetic minerals, including diamonds from the deep continental lithosphere and synthetic zeolites, which are important industrial catalysts.
