Patent number: 8987705Abstract: Carbon nanotubes can be aligned with compatibility with semiconductor manufacturing processes, with scalability for forming smaller devices, and without performance degradation related to structural damages. A planar structure including a buried gate electrode and two embedded electrodes are formed. After forming a gate dielectric, carbon nanotubes are assembled in a solution on a surface of the gate dielectric along the direction of an alternating current (AC) electrical field generated by applying a voltage between the two embedded electrodes. A source contact electrode and a drain contact electrode are formed by depositing a conductive material on both ends of the carbon nanotubes. Each of the source and drain contact electrodes can be electrically shorted to an underlying embedded electrode to reduce parasitic capacitance.Type: GrantFiled: January 9, 2014Date of Patent: March 24, 2015Assignees: International Business Machines Corporation, Karlsruher Institut fuer Technologie (KIT)Inventors: Phaedon Avouris, Yu-ming Lin, Mathias B. Steiner, Michael W. Engel, Ralph Krupke

Publication number: 20140061026Abstract: The invention provides a process for producing finely divided particles of core-shell structure where the shell comprises at least one polymer, said process comprising the steps of: i. providing a first aerosol stream of droplets in a carrier gas stream wherein the droplets comprise at least one monomer and charging droplets of the first aerosol with electric charge; ii. providing a second aerosol stream of solid particles in a carrier gas stream and charging the solid particles of the aerosol with an electric charge opposite to the electric charge on the droplets of the first aerosol stream; iii. mixing the first aerosol stream with the second aerosol stream to form a mixed aerosol stream; iv. initiating a polymerization of the monomers by irradiating this mixed aerosol stream with electromagnetic radiation. The invention also provides the finely divided particles of core-shell structure which are obtainable by this process.Type: ApplicationFiled: August 29, 2013Publication date: March 6, 2014Applicants: Karlsruher Institut fuer Technologie (KIT), BASF SEInventors: Wolfgang Gerlinger, Bernd Sachweh, Michael Woerner, Ertan Akguen, Stephanie Sigmund, Gerhard Kasper

Patent number: 8610989Abstract: A microcavity-controlled two-dimensional carbon lattice structure device selectively modifies to reflect or to transmit, or emits, or absorbs, electromagnetic radiation depending on the wavelength of the electromagnetic radiation. The microcavity-controlled two-dimensional carbon lattice structure device employs a graphene layer or at least one carbon nanotube located within an optical center of a microcavity defined by a pair of partial mirrors that partially reflect electromagnetic radiation. The spacing between the mirror determines the efficiency of elastic and inelastic scattering of electromagnetic radiation inside the microcavity, and hence, determines a resonance wavelength of electronic radiation that is coupled to the microcavity. The resonance wavelength is tunable by selecting the dimensional and material parameters of the microcavity. The process for manufacturing this device is compatible with standard complementary metal oxide semiconductor (CMOS) manufacturing processes.Type: GrantFiled: October 31, 2011Date of Patent: December 17, 2013Assignees: International Business Machines Corporation, Karlsruher Institut Fuer Technologie (KIT), Cambridge Enterprise LimitedInventors: Phaedon Avouris, Mathias B.
