Fujitsu Laboratories today announced, as a world first, the development of a novel technology for forming graphene transistors directly on the entire surface of large-scale insulating substrates at low temperatures while employing chemical-vapor deposition (CVD) techniques which are in widespread use in semiconductor manufacturing. http://www.physorg.com/news178552799.html Technology Fri, 27 Nov 2009 14:00:59 EST news178552799 Two-dimensional carbon layers, so-called graphenes, are regarded as a possible substitute for silicon in the semiconductor industry. The electronic properties of these layers can be varied by "building in" specific arrays of holes in their structure. Physicists at Empa, Switzerland, together with chemists from the Max Planck Institute for Polymer Research in Mainz, Germany, have, for the first time, succeeded in synthesizing a graphene-like porous polymer with atomic accuracy. http://www.physorg.com/news177871833.html Nanotechnology Thu, 19 Nov 2009 16:53:34 EST news177871833 (PhysOrg.com) -- First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. http://www.physorg.com/news177689867.html Nanotechnology Tue, 17 Nov 2009 14:22:12 EST news177689867 (PhysOrg.com) -- A Cornell research team has invented a simple way to make graphene electrical devices by growing the graphene directly onto a silicon wafer. http://www.physorg.com/news177062908.html Nanotechnology Tue, 10 Nov 2009 08:10:01 EST news177062908 A theoretical physicist at the National Institute of Standards and Technology has developed a method for calculating the motions and forces of thousands of atoms simultaneously over a wider range of time scales than previously possible. The method overcomes a longstanding timing gap in modeling nanometer-scale materials and many other physical, chemical and biological systems at atomic and molecular levels. http://www.physorg.com/news176555152.html Physics Wed, 04 Nov 2009 11:09:16 EST news176555152 (PhysOrg.com) -- MIT physicist Pablo Jarillo-Herrero has won a 2009 David and Lucile Packard Fellowship, an award he will use to study a new class of materials that could have applications in the semiconductor industry and quantum computing. http://www.physorg.com/news174894793.html Physics Fri, 16 Oct 2009 07:40:02 EST news174894793 UCL researchers are helping to unlock the secrets of a material that could ultimately be used in a new generation of electronic devices. http://www.physorg.com/news174852159.html Nanotechnology Thu, 15 Oct 2009 22:10:01 EST news174852159 Rutgers researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices. http://www.physorg.com/news174745964.html Nanotechnology Wed, 14 Oct 2009 13:33:58 EST news174745964 (PhysOrg.com) -- Physicists have investigated the purest graphene to date, and have found that the material possesses unprecedented high electronic quality. The discovery has raised the bar for this relatively new material, and challenges scientists to find out just how perfect graphene can be. http://www.physorg.com/news174654627.html Nanotechnology Tue, 13 Oct 2009 12:11:02 EST news174654627 (PhysOrg.com) -- In an effort to make graphene more useful in electronics applications, Kansas State University engineers made a golden discovery -- gold "snowflakes" on graphene. http://www.physorg.com/news174590038.html Nanotechnology Mon, 12 Oct 2009 18:15:28 EST news174590038 Researchers analyzing the assembly of graphene (sheets of carbon only one atom thick) on a surface of iridium have found that the sheets grow by first forming tiny carbon domes. The discovery offers new insight into the growth of graphene layers and points the way to possible methods for assembling components of graphene-based computer circuits. http://www.physorg.com/news174562394.html Nanotechnology Mon, 12 Oct 2009 10:50:01 EST news174562394 Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. The results will appear online on 4 October in Nature Physics. http://www.physorg.com/news173881546.html Nanotechnology Sun, 04 Oct 2009 13:26:35 EST news173881546 (PhysOrg.com) -- Researchers say they have found a simple way to improve the semiconducting properties of the world`s thinnest material - by giving it a good tug. http://www.physorg.com/news173340834.html Nanotechnology Mon, 28 Sep 2009 07:14:30 EST news173340834 Dr. Jiwoong Park of Cornell University, who receives funding for basic research from the Air Force Office of Scientific Research (AFOSR), is investigating carbon nanostructures that may some day be used in electronic, thermal, mechanical and sensing devices for the Air Force. http://www.physorg.com/news173036704.html Nanotechnology Fri, 25 Sep 2009 02:50:01 EST news173036704 (PhysOrg.com) -- Biomedical researchers suspect graphene, a novel nanomaterial made of sheets of single carbon atoms, would be useful in a variety of applications. But no one had studied the interaction between graphene and DNA, the building block of all living things.
