Impact of octahedral rotations on Ruddlesden-Popper phases of antiferrodistortive perovskites
Daniel A. Freedman, T. A. Arias
This work presents the most detailed and extensive theoretical study to date of the structural configurations of Ruddlesden-Popper (RP) phases in antiferrodistortive (AFD) perovski…

Elastic effects of vacancies in strontium titanate: Short- and long-range strain fields, elastic dipole tensors, and chemical strain
Daniel A. Freedman, D. Roundy, T. A. Arias
We present a study of the local strain effects associated with vacancy defects in strontium titanate and report the first calculations of elastic dipole tensors and chemical strain…

Cluster assimilation and collisional filtering on metal-oxide surfaces
Daniel A. Freedman, T. A. Arias
We present the first ab initio molecular dynamics study of collisions between metal-oxide clusters and surfaces. The resulting trajectories reveal that the internal degrees of free…
