Simulation of the Electrical Conductivity in Systems of Carbon Nanotubes
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 14 - Trang 1057-1060 - 2020
P. A. Likhomanova, K. Yu. Khromov
A simple and efficient method for calculating the conductivity of systems of carbon nanotubes forming a random resistor circuit in the case where the percolation threshold is reached in the system is proposed in this paper. This method uses the recursive removal of the dead-end branches of a cluster, which is necessary to determine the elements of the percolation cluster participating in the syste...... hiện toàn bộ
Effect of the Substrate Surface Roughness on the Stability of the Parameters of Thin-Film Resistive Elements
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 14 - Trang 875-881 - 2020
V. E. Sergeev, V. M. Vorotyntsev, T. S. Sazanova, I. V. Vorotyntsev, S. V. Kononov
In this paper, the effect of the substrate surface roughness on the stability of the parameters of thin-film resistive elements is investigated. The surface roughness of the substrates is determined by optical microscopy and atomic-force microscopy (AFM). A technology is developed to produce a smoothing surface coating based on thin Ta2O5 films with an amorphous coherent structure, the application...... hiện toàn bộ
Method of Laser Thermal Image Spectroscopy for Surface Diagnostics
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 13 - Trang 705-711 - 2019
S. A. Demin, V. T. Prokopenko, E. V. Shalobaev, A. V. Demin, A. S. Demina
A new method of laser-thermal imaging spectroscopy is presented and the results of studying samples with different absorption coefficients are reported. The times required for heating the surface of these samples by laser radiation with a wavelength of 0.634 µm to a temperature exceeding the initial value by 0.3°C are calculated and compared with the experimental data. The depths of laser-radiatio...... hiện toàn bộ
Nonlinear continual growth model of nonuniformly scaled reliefs as applied to the rigorous analysis of the X-ray scattering intensity of multilayer mirrors and gratings
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 8 - Trang 444-455 - 2014
L. I. Goray, M. N. Lubov
It is revealed that certain terms entering into the nonlinear continual equation describing thin-film growth enable its application to the simulation of the surfaces of multilayer mirrors and gratings with a large height and/or jumps of boundary-profile gradients. The proposed model characterizes both variations in the power spectral-density function of the surface of Al/Zr multilayer mirrors and ...... hiện toàn bộ
Electronic and optical characteristics of thin hexagonal gallium nitride films specified by surfaces
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 7 - Trang 1199-1206 - 2014
A. O. Litinski, S. I. Novikov, D. N. Zharikov
A computational procedure using density functional theory and generalized to the case of periodic finite-layered structures in the basis of valence orbitals with the inclusion of polarization functions is applied to calculation of the energy spectrum of electrons and curves for the optical absorption of thin hexagonal gallium-nitride films. It is shown that, to stabilize the atomically pure surfac...... hiện toàn bộ
Generalization of a nonstandard approach in dynamic diffraction theory to the case of deformed crystal
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 7 - Trang 56-61 - 2013
A. A. Dyshekov
A nonstandard X-ray diffraction theory for crystals taking lattice deformation into account is generalized in this paper. The vector of atomic-plane displacement is introduced in a model of crystal polarizability in analogy with the Takagi generalized dynamic theory. The solution of the wave equation is sought using the technique of expanding the field amplitude and vector operators in terms of th...... hiện toàn bộ
Finite-amplitude elastic waves interacting with temperature and nonequilibrium atomic defect fields
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 2 - Trang 669-676 - 2008
F. Kh. Mirzade
Nonlinear dynamics of one-dimensional longitudinal waves in isotropic elastic plates was studied taking into account the interaction of displacement fields, temperature, and concentration of nonequilibrium (relaxing) atomic point defects. A nonlinear evolution equation for describing the self-consistent field of longitudinal thermoelastic strain was derived. The effect of generation-recombination ...... hiện toàn bộ
Parameterization of the magnetite coating surfaces on low-carbon steel with the use of atomic force microscopy data

Structural Studies of the Qarakhanid Dirham Using X-Ray Diffraction and Neutron Tomography Methods
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 15 - Trang 1232-1237 - 2021
B. A. Abdurakhimov, M. Yu. Tashmetov, B. A. Bakirov, B. S. Yuldashev, S. E. Kichanov, D. P. Kozlenko, N. B. Ismatov
The structure and spatial distribution of corrosion in the volume of the medieval Qarakhanid dirham dated the X–XII century A.D. (Anno Domini) has been investigated using non-destructive structural X-ray diffraction and neutron tomography methods. The phase composition and their spatial distribution inside the coins were obtained. The main phase of the studied dirham is the silver-copper alloy wit...... hiện toàn bộ
