Theoretical study on proton diffusivity in Y-doped BaZrO3 with realistic dopant configurations

Autor: Shusuke Kasamatsu, Tetsuya Uda, Takeo Fujii, Kazuaki Toyoura

Publikováno v: Physical Chemistry Chemical Physics. 23:5908-5918

We theoretically revisit the proton diffusivity in yttrium-doped barium zirconate (Y-doped BaZrO3) with realistic dopant configurations under processing conditions. In a recent study employing the replica exchange Monte Carlo method, the equilibrium
