  • Patent number: 9035534
    Abstract: The electrical energy generating system of the present invention comprises a piece of alignment Buckypaper, an energy generator, a thin deposition and two contacts. The alignment Buckypaper is a thin sheet made from an aggregate of carbon nanotubes. The thin deposition is formed on at least one surface of the alignment Buckypaper by electrolysis to form a semimetal material. A contact is connected with the upper surface of the alignment Buckypaper and the other contact is connected with the lower surface of the alignment Buckypaper. In use, the energy generated by the generator is inputted to the alignment Buckypaper. The energy then ionizes the molecules contained in the alignment Buckypaper. The positive charges move to the upper contact and the negative charges move to the lower contact. Such electrical energy may then be fed to a load connected with the two contacts to do work on the load.

The ?dc/?opt ratio of such thim films may be improved via stable chemical doping and/or alloying of CNT-based films. The doping and/or alloying may be implemented in a large area coating system, e.g., on glass and/or other substrates. In certain example embodiments, a CNT film may be deposited and then doped via chemical functionalization and/or alloyed with silver and/or palladium. Both p-type and n-type dopants may be used in different embodiments of this invention. In certain example embodiments, silver and/or other nanowires may be provided, e.g., to further decrease sheet resistance. Certain example embodiments may provide coatings that approach, meet, or exceed 90% visible transmission and 90 ohms/square target metrics.

    Abstract: A multiple transistor differential amplifier is implemented on a single graphene nanoribbon. Differential amplifier field effect transistors are formed on the graphene nanoribbon from a first group of electrical conductors in contact with the graphene nanoribbon and a second group of electrical conductors insulated from, but exerting electric fields on, the graphene nanoribbon thereby forming the gates of the field effect transistors. A transistor in one portion of the differential amplifier and a transistor in another portion of the differential amplifier are responsive to an incoming electrical signal. A current source, also formed on the graphene nanoribbon, is connected with the differential amplifier, and the current source and the differential amplifier operating together generate an outgoing signal responsive to the incoming electrical signal.
