On the relevance between fine structure and enhanced performance of skutterudite thermoelectric materials: X-ray spectroscopy studies

This paper was to investigate the relevance between the fine structure and transport performance of thermoelectric materials, in which the atomic-scale fine structure and electronic structure of Ba and In double-filled skutterudites were characterized using extended X-ray absorption fine structure (EXAFS), X-ray absorption near-edge structure (XANES), and valence-band X-ray photoelectron spectroscopy (XPS).
