Scaling of the coercive field in ferroelectrics at the nanoscale
DOI: 10.7868/S0370274X13180070
Abstract
The scaling of the coercive field in ferroelectric films at the nanoscale is investigated experimentally. The scaling in the films of copolymer vinylidene fluoride and BaTiO3 with thickness equal by the order of value to the critical domain nucleus size 1-10 nm reveals deviation from the well known Kay and Dunn low. At this thickness region coercive field does not depend on thickness and coincides with Landau-Ginzburg-Devonshire value.
