  • LOW NOISE GRAPHENE HALL SENSORS, SYSTEMS AND METHODS OF MAKING AND USING SAME
    Publication number: 20160293834
    Abstract: Described examples include graphene Hall sensors, magnetic sensor systems and methods for sensing a magnetic field using an adjustable gate voltage to adapt the Hall sensor magnetic field sensitivity according to a control input for environmental or process compensation and/or real-time adaptation for balancing power consumption and minimum detectable field performance. The graphene Hall sensor gate voltage can be modulated and the sensor output signal can be demodulated to combat flicker or other low frequency noise. Also, graphene Hall sensors can be provided with capacitive coupled contacts for reliable low impedance AC coupling to instrumentation amplifiers or other circuits using integral capacitance.

  • METHOD AND APPARATUS FOR SORTING CARBON NANOTUBES
    Publication number: 20150307355
    Abstract: A process of sorting metallic single wall carbon nanotubes (SWNTs) from semiconducting types by disposing the SWNTs in a dilute fluid, exposing the SWNTs to a dipole-inducing magnetic field which induces magnetic dipoles in the SWNTs so that a strength of a dipole depends on a conductivity of the SWNT containing the dipole, orienting the metallic SWNTs, and exposing the SWNTs to a magnetic field with a spatial gradient so that the oriented metallic SWNTs drift in the magnetic field gradient and thereby becomes spatially separated from the semiconducting SWNTs. An apparatus for the process of sorting SWNTs is disclosed.

  • Graphene synthesis by chemical vapor deposition
    Patent number: 8470400
    Abstract: Processes for synthesizing graphene films. Graphene films may be synthesized by heating a metal or a dielectric on a substrate to a temperature between 400° C. and 1,400° C. The metal or dielectric is exposed to an organic compound thereby growing graphene from the organic compound on the metal or dielectric. The metal or dielectric is later cooled to room temperature. As a result of the above process, standalone graphene films may be synthesized with properties equivalent to exfoliated graphene from natural graphite that is scalable to size far greater than that available on silicon carbide, single crystal silicon substrates or from natural graphite.

  • Synthesizing graphene from metal-carbon solutions using ion implantation
    Patent number: 8461028
    Abstract: A method and semiconductor device for synthesizing graphene using ion implantation of carbon. Carbon is implanted in a metal using ion implantation. After the carbon is distributed in the metal, the metal is annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the surface of the metal. The metal/graphene surface is then transferred to a dielectric layer in such a manner that the graphene layer is placed on top of the dielectric layer. The metal layer is then removed. Alternatively, recessed regions are patterned and etched in a dielectric layer located on a substrate. Metal is later formed in these recessed regions. Carbon is then implanted into the metal using ion implantation. The metal may then be annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the metal's surface.
