Applications of High Spatial and Energy Resolution EELS in Functional Oxides for Thermoelectric Applications

Recent advances in instrumentation, such as the introduction of advanced, high-resolution monochromators have allowed for new exciting experiments in the electron microscope. Spectroscopic signatures of optical and acoustical phonons, excitons and defect gap states are now accessible with an atom size probe and in tandem with high precision imaging. Here, we present recent results on the phonon and electronic structure of thermoelectric (TE) materials systems for heat recovery applications, using advanced electron microscopy.<br/><br/>tobe expanded...
