Glass-like thermal conductivity in SrTiO3 thermoelectrics induced by A-site vacancies
arXiv:1411.0410 · doi:10.1039/C4RA06871H
Abstract
The introduction of A-site vacancies in SrTiO3 results in a glass-like thermal conductivity while Nb substituted samples maintains good electrical conductivity. This unexpected result brings SrTiO3 one step closer to being a high-performing phonon-glass electron-crystal thermoelectric material.
