Abstract
A method for producing a ferroelectric layer or antiferroelectric layer in which a layer of a paraelectric material already deposited on a surface of a substrate with a layer thickness of at least two crystallographic unit cells is introduced into an alternating electric field. The alternating electric field is repeatedly cycled between a positive electric field strength and a negative electric field strength of amplitude greater than the coercivity field strength of the material such that the layer of paraelectric material forms a polarization.
