钛酸锶氧缺陷热传导德拜模型SrTiO3 Oxygen Vacancies Thermal Conductivity Debye Model



In order to study the influence of oxygen vacancies in SrTiO3 on its thermal conductivity, SrTiO3 single crystals were annealed in high temperature under vacuum. The thermal conductivities of the as-received and annealed samples were determined by measuring their specific heat Cp of the samples using Differential Scanning Calorimetry (DSC) and their thermal diffusivities using Laser Flash Apparatus (LFA). The analysis showed that oxygen vacancies were generated during annealing which led to lower thermal conductivity, and the thermal conductivity properties of SrTiO3 conformed to the Debye model.
