Patent ID: 8866367

Claim:
An electrical device comprising: a substrate; a textured layer formed above the substrate; the textured layer comprising metal-oxide having a rocksalt structure with a {100}-texture that provides a heteroepitaxial template; a platinum film layer having {100}-texture crystal orientation formed on the textured layer; the platinum film layer crystallographic texture acting as a template; and at least one ferroelectric material layer exhibiting spontaneous polarization stylo-epitaxially deposited on the platinum film layer; whereby the rocksalt structure of the textured layer facilitates the growth of the platinum film layer with a {100} orientation which forms a template for stylo-epitaxial deposition of the ferroelectric layer such that the at least one ferroelectric layer is formed with an {001} orientation that increases the magnitude of the spontaneous polarization of the at least one ferroelectric layer.
