Method and media for improving ferroelectric domain stability in an information storage device

An information storage device comprising:

• a media, including:
• a bottom electrode layer;
• a ferroelectric layer arranged over the bottom electrode layer;
• and
• an overlayer arranged over the ferroelectric layer;
• wherein dipole charges generally having a first orientation exist at an interface between the bottom electrode layer and the ferroelectric layer;
• and
• wherein dipole charges generally having a second orientation opposite the first orientation exist at an interface between the ferroelectric layer and the over-layer;
• and
• a tip contactable with the over-layer;
• wherein the tip is in electrical communication with the ferroelectric layer through the over-layer.

A media for an information storage device comprising:

• a first layer of epitaxial film;
• a second layer of epitaxial film formed over the first layer;
• wherein an interface between the first layer and the second layer results in initial artifacts at the interface, the initial artifacts influencing a characteristic of the second layer;
• a third layer of epitaxial film formed over the second layer;
• wherein an interface between the second layer and the third layer results in compensating artifacts at the interface, the compensating artifacts at least partially reducing the influence of the initial artifacts on the characteristic of the second layer;
• and
• wherein the third layer of epitaxial film is accessible to a conductive tip and wherein the third layer is sufficiently thin such that the conductive tip electrically communicates with the second layer.

A media for an information storage device comprising:

• a first layer of epitaxial film;
• a second layer of epitaxial film formed over the first layer;
• wherein a first set of dipole charges generally having a first orientation exists at an interface between the first layer and the second layer;
• and
• a stabilizing layer of epitaxial film formed over the second layer;
• wherein a second set of dipole charges generally having a second orientation opposite the first orientation exists at an interface between the stabilizing layer and the second layer;
• and
• wherein the stabilizing layer of epitaxial film is accessible to a conductive tip and wherein the stabilizing layer is sufficiently thin such that the conductive tip electrically communicates with the second layer.
