Photovoltaic creation of charged domain walls in barium titanate
P. S. Bednyakov, P. V. Yudin, A. K. Tagantsev +1
The optical control of domain structures in ferroelectrics is of great interest. In the present work, we demonstrate the reliable creation of charged domain walls - conductive chan…
Paradoxical creation of a polydomain pattern by electric field in BaTiO3 crystal
Petr S. Bednyakov, Petr V. Yudin, Alexander K. Tagantsev +1
It is known that ferroelectric single crystals can be turned from a polydomain to a monodomain state by the application of an electric field. Here we report an unexpected opposite…
Impurity-induced Polar States in SrTiO3 Quantum Paraelectric
P. A. Markovin, V. A. Trepakov, M. E. Guzhva +5
Short and long range impurity-induced polar ordering in Sr1-xCaxTiO3 with x = 0.014 (SCT-1.4) and SrTi(16O0.0318O0.97)3 (STO-18) single crystals were investigated and discussed on…
Dynamic flexoelectric effect in perovskites from first principles calculations
Alexander Kvasov, Alexander K. Tagantsev
Using the dynamical matrix of a crystal obtained from ab initio calculations, we have evaluated for the first time the strength of the dynamic flexoelectric effect and found it com…
Impact of surface phenomena on direct bulk flexoelectric effect in finite samples
A. S. Yurkov, A. K. Tagantsev
In the framework of a continuum theory, it is shown that the direct flexoelectric response of a finite sample essentially depends on the surface polarization energy, even in the th…
Correlation Between Structure And C-Afm Contrast Of 180-Degree Domain Walls In Rhombohedral Bati03
Eugene A. Eliseev, Peter V. Yudin, Sergei V. Kalinin +3
Using Landau-Ginzburg-Devonshire theory we describe 180-degree domain wall structure, intrinsic energy and carrier accumulation in rhombohedral phase of BaTiO3 as a function of the…
