Structural, morphology and electrical properties of layered copper selenide thin film
Tập 7 - Trang 379-384 - 2009
Thin films of copper selenide (CuSe) were physically deposited layer-by-layer up to 5 layers using thermal evaporation technique onto a glass substrate. Various film properties, including the thickness, structure, morphology, surface roughness, average grain size and electrical conductivity are studied and discussed. These properties are characterized by X-ray diffraction (XRD), atomic force micro......
A theoretical forecast of the hydrogen bond changes in the electronic excited state for BN and its derivatives
Tập 10 - Trang 116-123 - 2011
The relationship between electronic spectral shifts and hydrogen-bonding dynamics in electronically excited states of the hydrogen-bonded complex is put forward. Hydrogen bond strengthening will induce a redshift of the corresponding electronic spectra, while hydrogen bond weakening will cause a blueshift. Time-dependent density function theory (TDDFT) was used to study the excitation energies in ......
A fluid generalization of membranes
- 2011
In a certain sense a perfect fluid is a generalization of a point particle. This leads to the question as to what is the corresponding generalization for extended objects. Here the lagrangian formulation of a perfect fluid is much generalized by replacing the product of the co-moving vector which is a first fundamental form by higher dimensional first fundamental forms; this has as a particular ex......
Notes on entropic characteristics of quantum channels
Tập 11 - Trang 69-77 - 2012
One of most important issues in quantum information theory concerns transmission of information through noisy quantum channels. We discuss a few channel characteristics expressed by means of generalized entropies. Such characteristics can often be treated in line with more usual treatment based on the von Neumann entropies. For any channel, we show that the q-average output entropy of degree q ≥ 1......
Growth and characterization of pulsed laser deposited ZnO thin films
Tập 5 - Trang 385-397 - 2007
One of the most important and promising materials from metal oxides is ZnO with specific properties for near UV emission and absorption optical devices. The properties of ZnO thin films strongly depend on the deposition method. Among them, pulsed laser deposition (PLD) plays an important role for preparing various kinds of ZnO films, e.g. doped, undoped, monocrystalline, and polycrystalline. Diffe......
C 1 non-integrability of a hydrogen atom in a circularly polarized microwave field
Tập 10 - Trang 742-748 - 2012
Barrabés et al. [Physica D, 241(4), 333–349, 2012] consider the problem of the hydrogen atom interacting with a circularly polarized microwave field modeled as a planar perturbed Kepler problem. For different values of the parameter, the authors offer some numerical evidence of the non-integrability of this problem. The objective of the present work is to give an analytical proof of the C1 non-int......
Effect of side walls on the motion of a viscous fluid induced by an infinite plate that applies an oscillating shear stress to the fluid
Tập 9 - Trang 816-824 - 2010
The velocity field corresponding to the unsteady motion of a viscous fluid between two side walls perpendicular to a plate is determined by means of the Fourier transforms. The motion of the fluid is produced by the plate which after the time t = 0, applies an oscillating shear stress to the fluid. The solutions that have been obtained, presented as a sum of the steady-state and transient solution......
Phenomenology of the nucleon-nucleon potential
Tập 8 - Trang 970-978 - 2010
A local nucleon-nucleon potential expansion is developed in terms of orthogonal projectors. Considering the nucleon-nucleon (NN) potential as a completely phenomenological structure, the expansion provides an opportunity to obtain the NN scattering phase shifts that can be described by applying a restricted set of operators, dependent on angular and spin-isospin degrees of freedom of the interacti......
Baryon and electric charge fluctuations at crossover
Tập 10 - Trang 1375-1378 - 2012
We discuss the higher order cumulants of net-baryon and electric charge fluctuations as a probe of the QCD crossover. The sensitivity of the higher order cumulants in the hadron resonance gas model to an inclusion of repulsive interactions is also considered.
Magnetism of free and supported clusters: a comparative study
Tập 7 - Trang 257-263 - 2008
The presented work investigates the differences in magnetic properties of free and supported clusters via ab-initio calculations. The electronic structure of the clusters was calculated using a spin polarized relativistic multiple-scattering Green’s function formalism. We focus on Fe clusters of 2–9 atoms, either free or supported by Ni(001), and on Co clusters of 2–7 atoms, either free or s......
