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
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
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
Some properties of the fundamental solution to the signalling problem for the fractional diffusion-wave equation Tập 11 - Trang 666-675 - 2013
Yuri Luchko, Francesco Mainardi
In this paper, the one-dimensional time-fractional diffusion-wave equation with
the Caputo fractional derivative of order α, 1 ≤ α ≤ 2 and with constant
coefficients is revisited. It is known that the diffusion and the wave equations
behave quite differently regarding their response to a localized disturbance.
Whereas the diffusion equation describes a process where a disturbance spreads

Photoacoustic spectroscopy for trace gas detection with cryogenic and room-temperature continuous-wave quantum cascade lasers Tập 8 - Trang 194-201 - 2009
Virginie Zeninari, Agnès Grossel, Lilian Joly, Thomas Decarpenterie, Bruno Grouiez, Bernard Bonno, Bertrand Parvitte
The main characteristics that a sensor must possess for trace gas detection and
pollution monitoring are high sensitivity, high selectivity and the capability
to perform in situ measurements. The photacoustic Helmholtz sensor developed in
Reims, used in conjunction with powerful Quantum Cascade Lasers (QCLs), fulfils
all these requirements. The best cell response is # 1200 V W−1 cm and the

Resistance simulations for junctions of SW and MW carbon nanotubes with various metal substrates Tập 9 - Trang 519-529 - 2010
Yuri N. Shunin, Yuri F. Zhukovskii, Natalia Burlutskaya, Stefano Bellucci
This theoretical study focuses on junctions between the carbon nanotubes (CNTs)
and contacting metallic elements of a nanocircuit. Numerical simulations on the
conductance and resistance of these contacts have been performed using the
multiple scattering theory and the effective media cluster approach. Two models
for CNT-metal contacts have been considered in this paper: a) first principles
