Charged States and Band-Gap Narrowing in Codoped ZnO Nanowires for Enhanced Photoelectrochemical Responses
Charged States Band-Gap Narrowing Codoped ZnO Nanowires Enhanced Photoelectrochemical Responses
2012/2/27
By means of first-principles calculations within the density functional theory, we study the structural and optical properties of codoped ZnO nanowires and compare them with those of the bulk and film...
On the probability of quantum phase slips in superconducting nanowires
quantum phase slips superconducting nanowires
2012/2/27
The paper discusses mechanisms for decay of supercurrents in ultrathin superconducting wires driven by quantum fluctuations. We argue that momentum conservation strongly suppresses probability of such...
Mathematical modeling of magnetostrictive nanowires for sensor application
sensor application magnetostrictive nanowires Materials Science
2011/9/30
Abstract: Magnetostrictive wires of diameter in the nanometer scale have been proposed for application as acoustic sensors [Downey et al., 2008], [Yang et al., 2006]. The sensing mechanism is expected...

The spin precession in a cylindrical semiconductor nanowire due to Rashba spin-orbit coupling has been investigated theoretically using an InAs nanowire containing a surface two-dimensional electron g...
Spin-orbit coupling and phase-coherence in InAs nanowires
Spin-orbit coupling phase-coherence InAs nanowires
2010/11/18
We investigated the magnetotransport of InAs nanowires grown by selective area metal-organic
vapor phase epitaxy. In the temperature range between 0.5 and 30 K reproducible fluctuations in the conduc...
Effect of quasi-bound states on coherent electron transport in twisted nanowires
quasi-bound states coherent electron transport twisted nanowires
2010/11/8
Quantum transmission spectra of a twisted electron waveguide expose the coupling between traveling and quasi-bound states. Through a direct numerical solution of the open-boundary Schr\"odinger equati...
Group-III assisted catalyst-free growth of InGaAs nanowires and the formation of quantum dots
Group-III assisted catalyst-free growth InGaAs nanowires quantum dots
2010/11/25
Growth of GaAs and InxGa1xAs nanowires by the group-III assisted Molecular Beam Epitaxy growth method is studied in dependence of growth temperature, with the objective of maximizing the ind...
Large enhancement in hole velocity and mobility in p-type [110] and [111] silicon nanowires by cross section scaling: An atomistic analysis
silicon nanowire mobility p-type holes atomistic bandstructure
2010/11/22
The mobility of p-type nanowires (NWs) of diameters of D=12nm down to D=3nm, in [100], [110], and [111] transport orientations is calculated. An atomistic tightbinding model is used to calculate the N...

Box Model for Hysteresis Loops of Arrays of Ni Nanowires
Nanowires Hysteresis Phenomenological model
2010/9/25
In the present work, by means of a phenomenological model, we simulate the hysteresis loop of an hexagonal array of Ni nanowires. Our model is based on the assumption that the hysteresis loop of a sin...
