Abstract
A method of domain patterning a body of ferroelectric material. The method includes the steps of adhering spaced conducting strips to a surface of said body; covering portions of said surface of said body between said strips with material which is insulative relative to electric current produced when an electric field configuration is created in said body and which controls the formation of fringe electric field components in said material; and applying potentials simultaneously to said conducting strips and to a surface of said insulative material to create an electric field configuration in said body whereby said strips define said electric field configuration within said body and wherein said insulating material between said strips defines a potential within said body which is generally the same as the potential applied to said conducting strips.
