Temperature-driven phase transitions in SrBiTaO from first-principles calculations
R. Machado, M. Sepliarsky, M. G. Stachiotti
The phase transition sequence of SrBiTaO is investigated using a shell model with parameters fitted to first-principles calculations. We show that the complex interplay…

Atomistic Model Potential for PbTiO3 and PMN by Fitting First Principles Results
M. Sepliarksky, Z. Wu, A. Asthagiri +1
We have developed a shell model potential to describe PbTiO3 and PbMg1/3Nb2/3O3 (PMN) by fitting to first-principles results. At zero pressure, the model reproduces the temperature…

Interface effects in ferroelectric PbTiO ultrathin films on a paraelectric substrate
M Sepliarsky, M. G. Stachiotti, R. L. Migoni
Interface effects on the ferroelectric behavior of PbTiO ultrathin films deposited on SrTiO substrate are investigated using an interatomic potential approach with paramete…
