Outline

This research aims to establish a method to visualize the nanoscale morphology, atomic structure and the temperature distribution in thermoelectric nanomaterials which are working by transmission electron microscopy and electron energy-loss spectroscopy. By this visualizing method, we will evaluate the effect of the surface morphology and interface structure of thermoelectric nanomaterials on their thermoelectric properties. In addition, we will clarify the origin of the degradation of the thermoelectric properties by environmental transmission electron microscopy observations of the structural changes in thermoelectric nanomaterials which are working in gases.
