A theoretical forecast of the hydrogen bond changes in the electronic excited state for BN and its derivatives Tập 10 - Trang 116-123 - 2011
Dandan Wang, Ce Hao, Se Wang, Hong Dong, Jieshan Qiu
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 ... hiện toàn bộ
Notes on entropic characteristics of quantum channels Tập 11 - Trang 69-77 - 2012
Alexey E. Rastegin
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... hiện toàn bộ
A fluid generalization of membranes - 2011
Mark D. Roberts
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... hiện toàn bộ
Phase transition and high pressure behavior of Zirconium and Niobium carbides Tập 7 - Trang 102-107 - 2008
Archana Singh, Mahendra Aynyas, Sankar P. Sanyal
We have predicted the phase transition pressure (P T )and high pressure behavior
of Zirconium and Niobium carbide (ZrC, NbC). The high pressure structural phase
transitions in ZrC and NbC has been studied by using a two body inter-ionic
potential model, which includes the Coulomb screening effect, due to the
semi-metallic nature of these compounds. These transition metal carbides have
been found t... hiện toàn bộ
Structural, morphology and electrical properties of layered copper selenide thin film Tập 7 - Trang 379-384 - 2009
J. Ying Chyi Liew, Zainal A. Talib, W. Mahmood, M. Yunus, Zulkarnain Zainal, Shaari A. Halim, Mohd M. Moksin, Wan Mohd Yusoff, K. Pah Lim
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... hiện toàn bộ
Analysis of A-DLTS spectra of MOS structures with thin NAOS SiO2 layers Tập 9 - Trang 242-249 - 2010
Peter Hockicko, Peter Bury, Peter Sidor, Hikaru Kobayashi, Masao Takahashi, Takashi Yanase
A set of MOS structures with thin SiO2 layers prepared by nitric acid oxidation
(NAOS) method was investigated using acoustic deep level transient spectroscopy
(A-DLTS) to explain the role of annealing treatment (post-oxidation annealing
(POA) and post-metallization annealing (PMA)) at different conditions on the
distribution of interface states. The activation energies of interface states
and the... hiện toàn bộ
Experimental Stark broadening studies of the CI transition 3s 1 P 1 o − 3p 1 S 0 at 833.5 nm - 2010
Agnieszka Bartecka, Adam Bacławski, Józef Musielok
Experimental Stark broadening studies of the infrared CI transition 3s 1 P 1 −
3p 1 S 0 at 833.5 nm are reported for the first time. A high-current
wall-stabilized arc, operated in a mixture of helium, argon, carbon dioxide and
hydrogen, was applied as the plasma source. Radiation emitted from homogeneous
and optically thin plasma layers was analyzed. Stark broadening studies of the
selected CI tr... hiện toàn bộ
Magnetostructural transformations in Ni51Mn36Sn13 Heusler alloy thin films Tập 9 - Trang 558-561 - 2011
Karol Załęski, Janusz Dubowik, Iwona Gościańska, Bartłomiej Andrzejewski, Tomasz Toliński
In this paper we report structural, magnetic and transport properties of
strongly textured Ni51Mn36Sn13 thin films. The off-stoichiometric Heusler alloy
films with 200 nm thickness were sputter-deposited on a MgO(100) substrate at
500 K and after annealed at 1000 K in UHV conditions. The textured growth was
confirmed by x-ray diffraction in Bragg-Brentano geometry. The temperature
dependence of th... hiện toàn bộ
Concentration of radiation displacement defects in BSO and BGO crystals irradiated by electrons or neutrons Tập 6 - Trang 52-56 - 2008
Piotr Potera
This work is devoted to the calculation of the concentration of radiation
displacement defects (RDD) in bismuth germanate and bismuth silicate crystals as
a function of particle energy (electrons and neutrons). Energy dependencies of
RDD concentrations are discussed in comparison with results for other complex
oxide crystals. The obtained results show that for the case of electron
irradiation the ... hiện toàn bộ
The Klein-Gordon equation with the Kratzer potential in d dimensions Tập 6 - Trang 717-729 - 2008
Nasser Saad, Richard L. Hall, Hakan Ciftci
We apply the Asymptotic Iteration Method to obtain the bound-state energy
spectrum for the d-dimensional Klein-Gordon equation with scalar S(r) and vector
potentials V(r). When S(r) and V(r) are both Coulombic, we obtain all the exact
solutions; when the potentials are both of Kratzer type, we obtain all the exact
solutions for S(r) = V(r); if S(r) > V(r) we obtain exact solutions under
certain co... hiện toàn bộ
