Mechanism for puddle formation in graphene

December 5, 2011
Author(s)
Shaffique Adam, Suyong S. Jung, Nikolai N. Klimov, Nikolai B. Zhitenev, Joseph A. Stroscio, Mark D. Stiles
Close to charge neutrality, graphene's energy landscape is highly inhomogeneous, forming a sea of electron-like and hole-like puddles that determine the properties of graphene at low carrier density. However, the details of puddle formation have remained

On-chip, photon-number-resolving, telecommunication-band detectors for scalable photonic information processing

December 5, 2011
Author(s)
Thomas Gerrits, Nick Thomas-Peter, James Gates, Adriana E. Lita, Benjamin Metcalf, Brice R. Calkins, Nathan A. Tomlin, Anna E. Fox, Antia A. Lamas-Linares, Justin Spring, Nathan Langford, Richard P. Mirin, Peter Smith, Ian Walmsley, Sae Woo Nam
Integration is currently the only feasible route towards scalable photonic quantum processing devices which are sufficiently complex to be genuinely useful in computing, metrology, and simulation. Embedded on-chip detection will be critical to such devices

Reversible effect of strain on transport critical current in Bi 2 Sr 2 CaCu 2 O 8+x superconducting wires: A modified descriptive strain model

December 5, 2011
Author(s)
Najib Cheggour, Xifeng Lu, T G. Holesinger, Theodore C. Stauffer, J Jiang, Loren F. Goodrich
A reversible strain effect on transport critical current I c was found in Bi 2Sr 2CaCu 2O 8+x (Bi-2212) high-temperature superconducting round wires. I c showed unambiguous reversibility at 4 K and 16 T up to an irreversible strain limit of about 0.3 % in

Versus: A Framework for General Content-Based Comparisons

December 5, 2011
Author(s)
Peter Bajcsy, Antoine Vandecreme, Benjamin J. Long, Paul Khouri Saba, Joe Chalfoun, Luigi Marini, Devin Bonnie, Rob Kooper, Michal Ondrejcek, Kenton McHenry
Abstract—We present a framework for the execution and dissemination of customizable content-based file comparison methods. Given digital objects such as files, database entries, or in-memory data structures, we are interested in establishing their

Recommended Auger Parameters for 42 Elemental Solids

December 4, 2011
Author(s)
Cedric J. Powell
Values of the Auger parameter are presented for 42 elemental solids. These values were determined from evaluated Auger-electron kinetic energies and photoelectron binding energies (BEs). Small adjustments were made to earlier values of photoelectron BEs to

MOSFETs made from GaN nanowires with fully conformal cylindrical gates

December 2, 2011
Author(s)
Paul T. Blanchard, Kristine A. Bertness, Todd E. Harvey, Aric W. Sanders, Norman A. Sanford, Steven M. George, Dragos Seghete
We report novel metal-oxide-semiconductor field effect transistors (MOSFETs) based on individual gallium nitride (GaN) nanowires with fully conformal cylindrical gates. The W/Al 2O 3 gates were deposited by atomic layer deposition. Reverse-bias breakdown

A Large-Signal Model of Ferroelectric Thin-Film Transmission Lines"

December 1, 2011
Author(s)
Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nate Orloff, James Booth, Juan M. O'C allaghan
"This work evaluates the microwave nonlinear properties and tuning at RF frequencies of ferroelectric Ba0.3Sr0.7TiO3 thin-films by on-wafer measurements of the second and third-order harmonics and intermodulation products of several coplanar transmission
