Molecular dynamics investigation of oxide ion transport in Sr-doped LaMnO3 |
|
Answer» A comprehensive investigation of OXIDE ion transport in La1−xSrxMnO3−0.5x (x = 0.2 and 0.5) over the temperature RANGE of 800–2000 K is carried out employing long molecular dynamics simulations. The macroscopic structural and transport properties are in good AGREEMENT with previous experimental studies. The role of La/Sr ordering on oxide ion diffusivity is investigated. Fresh insights on diffusion pathways, MICROSCOPIC energetics and MECHANISM of oxide ion transport are derived. |
