Thermal Conductivity: Glass‐Like Through‐Plane Thermal Conductivity Induced by Oxygen Vacancies in Nanoscale Epitaxial La0.5Sr0.5CoO3−δ (Adv. Funct. Mater. 47/2017)

Year: 2017

Type: article

Abstract: In article 1704233, Xiaojia Wang and co-workers demonstrate that single crystal La0.5Sr0.5CoO3−δ films possess a glass-like thermal conductivity through their plane. A combination of oxygen vacancies, Sr distribution, size effect, and weak electron/phonon coupling causes this effect. This discovery opens possibilities for tuning the thermal properties of perovskite thin films by manipulating heat carriers via structural/defect engineering at the atomic level.
