Simulation of the Electrical Conductivity in Systems of Carbon NanotubesJournal 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 ElementsJournal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 14 - Trang 875-881 - 2020

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 DiagnosticsJournal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 13 - Trang 705-711 - 2019

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
Diffracted channeling radiation for axial electron channelingJournal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 4 - Trang 823-830 - 2010
K. B. Korotchenko, Yu. L. Pivovarov, T. A. Tukhfatullin, E. I. Fiks
It is shown that, in contrast to diffracted channeling radiation (DCR) in the case of planar channeling, transitions of type 2 → 1, 3 → 2, 4 → 3, and so on make the main contribution to DCR in the case of axial channeling along an isolated axis. The angular DCR distributions for channeling of electrons with the energy corresponding to the Lorentz factor γ = 100 are calculated for an isolated axis ...... hiện toàn bộ
Electronic and optical characteristics of thin hexagonal gallium nitride films specified by surfacesJournal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 7 - Trang 1199-1206 - 2014

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
Features of Oxidation of Ar+-Ion-Irradiated GaAsJournal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques - Tập 16 - Trang 884-889 - 2022
A. P. Solonitsyna, E. A. Makarevskaya, D. A. Novikov, V. M. Mikoushkin
The features of oxidation of the surface of GaAs irradiated by low-energy Ar+ ions is considered based on elemental and chemical-composition analyses, calculations of the concentration profiles for radiation-induced defects, and estimations of radiation-enhanced diffusivities and diffusion lengths. The native oxide layer is revealed to be highly enriched with Ga (by a factor of 1.5) due to the rad...... hiện toàn bộ
Generalization of a nonstandard approach in dynamic diffraction theory to the case of deformed crystalJournal 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
