Research Contents : The JQH 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 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 research areas: Transmission Electron Microscopy; Thermoelectric Materials; Structure-property Relationship.
