چکیده

Thermoelectric energy conversion is widely recognized as a promising technology both for electric power generation in terms of waste heat recovery and for cooling of various electronic devices [1]. SrTiO3 based perovskites are among a number of candidate materials for such thermoelectric applications [2]. For the first time, we demonstrate the successful synthesis of (1-x)SrTiO3-xLa1/3NbO3 ceramics that exhibit excellent thermoelectric properties and we have used STEM-EELS in order to assess the quantitative effects of composition on the structure and properties of these materials.

Studying Dynamics of Oxygen Vacancy Ordering in Epitaxial LaCoO3 / SrTiO3 Superlattice with Real-Time Observation

Oxygen vacancies in perovskite oxides are of great interest both from fundamental viewpoint due to their effect on electronic and magnetic properties of oxides – and from applications viewpoint due to their importance for solid oxide fuel cells. In the latter case, understanding the dynamic behavior of vacancies is crucial. Oxygen vacancy (Vo) ordering can substantially affect local structure a...

Correlation Between Oxygen Vacancy, Microstrain, and Cation Distribution in Lithium-Excess Layered Oxides During the First Electrochemical Cycle

Dynamic structural changes during the first electrochemical charge and discharge cycle in the Li-excess layered oxide compound, Li[Li1/5Ni1/5Mn3/5]O2, are studied with synchrotron X-ray diffraction (SXRD), aberration corrected scanning transmission electron microscopy (a-S/TEM), and electron energy loss spectroscopy (EELS). At different states of charge, we carefully examined the crystal struct...

Crystal chemistry of hydrous forsterite and its vibrational properties up to 41 GPa

The crystal structure of hydrous pure magnesium forsterite (Mg2SiO4) containing 8900 ppmw H2O, synthesized at 12 GPa and 1250 °C, has been refined. The major hydration mechanism appears to be M1 cation vacancy with protonation of the O1-O2 octahedral edge of M1. Raman spectra up to 41 GPa show strong coupling between the two Ag modes (824.4 and 856.2 cm–1). Mode Grüneisen parameters γi related ...
