Our research group focuses on applying/developing varied advanced transmission electron microscopy techniques (HADDF, HREM, EELS, EDS, Lorentz TEM, electron holography, electron tomography, in situ TEM and so on) to determine the nanostructures/atomic structure of materials (mainly energy materials), thus providing insight into observed physical properties. This is of particular importance as electronic devices scale to ever vanishingly small dimensions, when the detailed arrangement of atoms at interfaces even inside materials begins to critically influence material properties. We focus on three areas: Nanostructured energy materials including the nanostructure of thermoelectrics, photovoltaics, fuel cells and batteries, and their real-time evolution during operation; Phase separation in strongly correlated electron systems; Interfacial structures.Our research group focuses on applying/developing varied advanced transmission electron microscopy techniques (HADDF, HREM, EELS, EDS, Lorentz TEM, electron holography, electron tomography, in situ TEM and so on) to determine the nanostructures/atomic structure of materials (mainly energy materials), thus providing insight into observed physical properties.
