Electrostriction at the LaAlO3/SrTiO3 interface.
We present a direct comparison between experimental data and ab initio calculations for the electrostrictive effect in the polar LaAlO(3) layer grown on SrTiO(3) substrates. From the structural data, a complete screening of the LaAlO(3) dipole field is observed for film thicknesses between 6 and 20 uc. For thinner films, an expansion of the c axis of 2% matching the theoretical predictions for ...
متن کاملElectrostriction Effects During Defibrillation
Background—The electric field applied to the heart during defibrillation causes mechanical forces (electrostriction), and as a result the heart deforms. This paper analyses the physical origin of the deformation, and how significant it is. Methods—We represent the heart as an anisotropic cylinder. This simple geometry allows us to obtain analytical solutions for the potential, current density, ...
متن کاملElectrostriction in elastic dielectrics undergoing large deformation
We develop a thermodynamic model of electrostriction for elastic dielectrics capable of large deformation. The model reproduces the classical equations of state for dielectrics at small deformation, but shows that some electrostrictive effects negligible at small deformation may become pronounced at large deformation. The model is then specialized to account for recent experiments with an elast...
متن کاملProtein hydration and the huge electrostriction.
Recent experiments indicated the existence of hydration shells about biomolecules with densities markedly higher than that of bulk water. The compression is due to the pull of the dipoles of H(2)O molecules, necessary to achieve the thermodynamic equilibrium, from bulk water into the high field (approx. 10(9) V/m) region at the surface of the protein molecule. The electric field values at the s...
متن کاملInterferometric investigation of quadratic electrostriction in solid dielectrics
Electrostriction Is the strain response of a dlelectric material proportional to the square of an applled electric field. Thls effect Is related to 1he straindependence of 1he dlelectric function. The strain signal observed using optical inlerlerometry is a superposition of true electrostriction and other effects llke electrostalie lorces and thennal stresses. Therelore, ~Is necessary to have a...
