First-Principles Description of Oxygen Self-Diffusion in Rutile TiO2: Assessment of Uncertainties due to Energy and Entropy Contributions

12-Jun-2018 | Heonjae Jeong; Edmund G Seebauer; Elif Ertekin, Physical Chemistry Chemical Physics, 2018

Properties related to transport such as self-diffusion coefficients are relevant to fuel cells, electrolysis cells, and chemical/gas sensors. Prediction of self-diffusion coefficients from first-principles involves precise determination of both enthalpy and entropy contributions for point defect ...
