Abstract: An arrangement, a method and a system to read information stored in a layer of ferroelectric media. The arrangement includes a layer including a ferroelectric media having one or more ferroelectric domains holding bit charges, a domain corresponding to information; a probe having a tip, wherein the media and the tip are adapted to move relative to one another such that the tip scans the ferroelectric domains of the media while applying a contact force to the domains to generate a direct piezoelectric effect within the domains; and circuitry coupled to the tip and adapted to generate a signal in response to an electrical coupling between the tip and the domains while scanning the tip in contact with the domains, the signal corresponding to a readout signal for ferroelectric bit charges stored in the media.

Abstract: According to embodiments of the present invention, a probe storage medium includes a conductive layer as an electrode and a metal, metalloid, and/or non-metal doped diamond-like carbon (DLC) layer disposed on the conductive layer. A probe array may be positioned close proximity with the layer of doped DLC. An individual probe in the probe array may have an atomic force microscope tip. The probe storage medium may be written to by applying a current, voltage, and/or power to the tip between a thresholds current, voltage, and/or power value and a limiting current, voltage, and/or power value. The current, voltage, and/or power cause the layer of DLC to change conductance. The probe storage medium may be read by applying a current, voltage, and/or power to the tip below a threshold current, voltage, and/or power value and sensing the conductance.

Abstract: A device to detect polarization of a ferroelectric material comprises a probe tip, a charge amplifier electrically connected with the probe tip to convert a charge coupled to the probe tip from the ferroelectric material into an output voltage. The ferroelectric material is oscillated at a reference signal so that a charge is coupled to the probe tip and converted to an output voltage by the charge amplifier. A lock-in amplifier that receives the reference voltage and applies the reference voltage to the output voltage to extract a signal output representing the polarization.

Abstract: A media for storing information comprises a substrate, a conductive layer formed over the substrate, and a ferroelectric layer epitaxially formed on the conductive layer. The ferroelectric layer includes an a-lattice constant that is substantially matched to an a-lattice constant of the conductive layer and an average c-lattice constant that is longer than an average c-lattice constant of a bulk-grown ferroelectric layer.

Abstract: A system for storing information comprises a media including a ferroelectric layer and a passivation layer formed over the ferroelectric layer, and a tip arranged in approximate contact with the passivation layer. The tip detects a polarization signal that corresponds to changes in polarization of domains of the ferroelectric layer.

Abstract: A method of forming a passivation layer over a ferroelectric layer of a ferroelectric media comprises introducing the ferroelectric layer to a plasma comprising one of oxygen, oxygen-helium, and oxygen-nitrogen-helium, etching a surface of the ferroelectric layer, forming one of a substantially oxygen enriched layer and a substantially hydroxyl enriched layer at the surface of the ferroelectric layer, introducing the ferroelectric layer to an environment comprising substantially nitrogen, and maintaining the ferroelectric layer within the environment so that nitrogen enriches the substantially oxygen enriched layer to form a passivation layer.
