Ab initio phase diagram of BaTiO under epitaxial strain revisited
Anna Grünebohm, Madhura Marathe, Claude Ederer
We revisit the phase diagram of BaTiO under biaxial strain using a first principles-based effective Hamiltonian approach. We show that, in addition to the tetragonal (), qua…
Positive and negative electrocaloric effect in BaTiO in the presence of defect dipoles
Yang-Bin Ma, Anna Grünebohm, Kai-Christian Meyer +2
The influence of defect dipoles on the electrocaloric effect (ECE) in acceptor doped BaTiO is studied by means of lattice-based Monte-Carlo simulations. A Ginzburg-Landau type…
First principles-based calculation of the electrocaloric effect in BaTiO: comparison between direct and indirect methods
Madhura Marathe, Anna Grünebohm, Takeshi Nishimatsu +2
We use molecular dynamics simulations for a first principles-based effective Hamiltonian to calculate two important quantities characterizing the electrocaloric effect in BaTiO…
Influence of defects on ferroelectric and electrocaloric properties of BaTiO
Anna Grünebohm, Takeshi Nishimatsu
We report modifications of the ferroelectric and electrocaloric properties of BaTiO by defects. For this purpose, we have combined \textit{ab initio}-based molecular dynamics s…
