Optimization of solution-processed oligothiophene:fullerene based organic solar cells by using solvent additives
(Beilstein Institut, 2013-10)
The optimization of solution-processed organic bulk-heterojunction solar cells with the acceptor-substituted quinquethiophene DCV5T-Bu-4 as donor in conjunction with PC61BM as acceptor is described. Power conversion ...
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)
The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ...
Effect of surface plasmon resonance in TiO2/Au thin films on the fluorescence of self-assembled CdTe QDs structure
(IOP Publishing, 2015)
The exceptional properties of localised surface plasmons (LSPs), such as local field enhancement and confinement effects, resonant behavior, make them ideal candidates to control the emission of luminescent nanoparticles. ...
Magnetization reversal and exchange bias effects in hard/soft ferromagnetic bilayers with orthogonal anisotropies
(IOP Publishing LTD, 2012-11-02)
The magnetization reversal processes are discussed for exchange-coupled ferromagnetic hard/soft bilayers made from Co0.66Cr0.22Pt0.12 (10 and 20 nm)/Ni (from 0 to 40 nm) films with out-of-plane and in-plane magnetic easy ...
Acoustic plasmons in extrinsic free-standing graphene
(IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
(IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ...
Computational study of the vortex path variation with the VG height
(IOP Publishing, 2014)
An extensive range of conventional, vane-type, passive vortex generators (VGs) are in use for successful applications of flow separation control. In most cases, the VG height is designed with the same thickness as the local ...
Metallic thin films on stepped surfaces: lateral scattering of quantum well states
(IOP Publishing, 2014-12-10)
Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe ...
Digital Quantum Simulation of Spin Models with Circuit Quantum Electrodynamics
(American Physical Society, 2015-06-17)
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventional computers poses significant challenges. ...
Dual-path methods for propagating quantum microwaves
(IOP Publishing, 2014-01)
We study quantum state tomography, entanglement detection and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use of the following key elements: propagation ...
