Ab initio and classical simulations of defects in SrTiO3

Nov 01,2001·Both the empirical and the ab initio methods predicted that the AFD phase should be more energetically stable.However,the rotation angle of the oxygen octahedra was over estimated compared to the experimental data (Table 2,Table 3,Table 4).The observed rotation angle is only about 2° as cited by Hayward and Salje .In the ab initio calculation the rotations were accompanied byAb initio electronic and magnetic structure in La 0.66 Sr The effects of tetragonal strain on the electronic and magnetic properties of strontium-doped lanthanum manganite,La 2/3 Sr 1/3 MnO 3 (LSMO),are investigated by means of density-functional methods.As far as the structural properties are concerned,the comparison between theory and experiments for LSMO strained on the most commonly used substrates shows an overall good agreement the slight Ab initio instanton rate theory made efficient using Ab initio instanton rate theory is a computational method for rigorously including tunnelling effects into the calculations of chemical reaction rates based on a potential-energy surface computed on the fly from electronic-structure theory.This approach is necessary to extend conventional transition-state theory into the deep-tunnelling regime,but it is also more computationally expensive as
