Ferroelectric Phase Transitions in Ultra-thin Films of BaTiO3

Autor: Paul, Jaita, Nishimatsu, Takeshi, Kawazoe, Y., Waghmare, Umesh V.

We present molecular dynamics simulations of a realistic model of an ultrathin film of BaTiO$_3$ sandwiched between short-circuited electrodes to determine and understand effects of film thickness, epitaxial strain and the nature of electrodes on its

International audience; We have studied the energetics, relaxation and interactions of steps on the Au(332) vicinal surface, using a combination of grazing incidence X-ray diffraction (GIXD), anisotropic linear elasticity (ALE) theory, and ab initio
