Ferroelectric and piezoelectric ceramics used in different electromechanical devices are often subject to various source of stresses in their working environment. Experimental results reveal that the electromechanical behavior of these materials can be tremendously altered in the presence of stress. In this paper, we present a theoretical investigation on the effect of uniaxial compressive stress...
The role of space charge induced in a ferroelectric thin film and the presence of Schottky barriers at the two electrode/film interfaces are studied by numerical simulation using Landau-Khalatnikov theory. In this work, the whole film is considered as the stacking of dipolar layers, each of which contains multilayers of perovskite cells. In the presence of a local electric field, the double-well thermodynamic...
