Ferroelectric Behavior of Nano-Layered Heterostructures Composed of Ferroelectric - Linear Dielectric Organic Layers

摘要

Thin-film heterostructures comprising ferroelectric (FE) copolymer layers of vinylidene fluoride withudtrifluoroethylene (PVDF/TrFE) and linear dielectric (LD) layers of azodye prepared by Langmuir-Blodgettudtechnique are obtained and studied. A simple physical model of a local electric field amplification in layersudof FE and LD are presented. Experimental studies of the ferroelectric switching confirm that, for heterostructures,udthe external effective coercitive voltage decreases and the switched polarization increases.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35144
