A media for an information storage device includes a substrate of
single-crystal silicon, a buffer layer of an epitaxial single crystal
insulator formed over the substrate, a bottom electrode layer of an
epitaxial single crystal conductor formed over the buffer layer, a
ferroelectric layer of an epitaxial single crystal ferroelectric material
formed over the bottom electrode layer, and an overlayer of an epitaxial
single crystal material formed over the ferroelectric layer. Dipole
charges generally having a first orientation exist at an interface
between the bottom electrode layer and the ferroelectric layer includes,
while dipole charges generally having a second orientation opposite the
first orientation exist at an interface between the ferroelectric layer
and the overlayer includes.
