By: I. V. Konoplev, P. Maclnnes, A. W. Cross, A. D. R. Phelps, L. Fisher et al

Description: The phenomenon of tunneling manifests itself in nearly every field of physics. The ability to distinguish a wave tunneling through a barrier from one propagating is important for a number of applications. Here we explore the properties of the wave traveling through the band gap created by a lattice, either as a consequence of tunneling through the barrier or due to the presence of a pass band inside the gap. To observe the pass band for studying tunneling an...

By: Goki Eda, H. Emrah Unalan, Nalin Rupesinghe, Gehan A. Amaratunga, and Manish Chhowalla

Description: Field emission from graphene is challenging because the existing deposition methods lead to sheets that lay flat on the substrate surface, which limits the field enhancement. Here we describe a simple and general solution based method for the deposition of field emitting graphene/polymer composite thin films. The graphene sheets are oriented at some angles with respect to the substrate surface leading to field emission at low threshold fields ( ∼ 4 V μm−1). ...

By: R. Kögler, X. Ou, W. Skorupa, and W. Möller

Description: The excess of implantation-induced point defects controls the oxygen redistribution in silicon during a high-temperature treatment, such as in separation-by-implanted-oxygen, and defines the energy-dose window for the formation of a perfect homogeneous and planar buried oxide layer. Quantitative relations are given between the distribution of the initially generated excess defects and the finally formed oxide layer. Implantation-induced defects also explain ...

By: Manuel J. Freire, Ricardo Marques, and Lukas Jelinek

Description: In this work a μ =−1 metamaterial MM lens for magnetic resonance imaging MRI is demonstrated. MRI uses surface coils to detect the radio frequency rf energy absorbed and emitted by the nuclear spins in the imaged object. The proposed MM lens manipulates the rf field detected by these surface coils so that the coil sensitivity and spatial localization are substantially improved. Beyond this specific application, we feel that the reported results are th...

By: Kisam Park, Bill Poirier, and Gérard Parlant

Description: Quantum trajectory methods (QTMs) hold great promise as a potential means of obtaining dynamical insight and computational scaling similar to classical trajectory simulations but in an exact quantum dynamical context. To date, the development of QTMs has been stymied by the “node problem”—highly nonclassical and numerically unstable trajectories that arise when the wavepacket density |ψ|2 exhibits substantial interference oscillations. In a recent paper, how...

By: M. Pivi, F. K. King, R. E. Kirby, T. O. Raubenheimer, G. Stupakov et al

Description: The effect of an artificially enhanced rough surface on the secondary electron yield (SEY) was investigated both theoretically and experimentally. Analytical studies on triangular and rectangular grooved surfaces show the connection between the characteristic parameters of a given geometry to the SEY reduction. The effect of a strong magnetic field is also discussed. SEY of grooved samples have been measured and the results agree with particle simulations us...

By: Z. Olszewski, R. Houlihan, C. Ryan, C. OMahony, and R. Duane

Description: DC and bipolar voltage stresses are used to isolate mechanical degradation of the movable electrode from charging mechanism in microelectromechanical capacitive switches. Switches with different metals as the movable electrode were investigated. In titanium switches, a shift in the pull-in voltages is observed after dc stressing whereas no shift occurs after the bipolar stressing, which is to be expected from charging theory. On switches with similar dielect...

By: N. H. March and Á. Nagy

Description: Following some studies of ∫ n(r)∇V(r)dr by earlier workers for the density functional theory (DFT) one-body potential V(r) generating the exact ground-state density, we consider here the special case of spherical atoms. The starting point is the differential virial theorem, which is used, as well as the Hiller–Sucher–Feinberg [ Phys. Rev. A 18, 2399 (1978) ] identity to show that the scalar quantity paralleling the above vector integral, namely, ∫ n(r)∂V(r)/...
