The energy spectra of electrons reflected from multilayer targets are studied theoretically and experimentally. A self-consistent theory of electron reflection from multilayer surfaces is constructed. Simple analytical models of electron reflection that illustrate the feasibility of the depth profiling of multilayer targets are presented. The energy spectra of electrons normally incident on Nb/Si and Nb/Al/Nb/Si targets and reflected from them at an angle of 45° to the normal are taken. A method for the depth profiling of such structures is elaborated. 相似文献

Giant nonlinear refraction has been experimentally observed in gold island films. The real part of the third-order nonlinear susceptibility χ(3)(ω: ω,-ω, ω) reaches a value of about 10?4 CGS units. The mechanism of nonlinearity of the refractive index can be associated with the resonance enhancement of the factor of the local optical field at the pump wavelength due to the excitation of surface plasmons, as well as with the contribution of the heating of conduction electrons in an ensemble of metal particles. 相似文献

1. Dislocations in magnetic flux-grown garnet crystals (Y3Fe5O12 and others) have been observed. As a rule, {110} growth pyramids have more defects than {211} ones. 2. The highest content of defects (dislocation density 103–104 cm−2) is observed in Y3Fe5O12 that grows on crucible walls adjacent to the free surface of the solution where the flow of heat is not uniform to the greatest degree. Bottom grown crystals usually have less dislocations. Far fewer dislocations are in wall grown crystals, least of all dislocations are contained in crystals that grow inside the solution. The solution pouring off at the end of the crystallization period increases dislocation density by some dozens. 3. Heat treatment decreases dislocation density. The less dislocation content and the lower ordering are in the initial crystal, the higher heat treatment effectiveness. 相似文献

On the basis of the absolute reaction rates theory and the Brønsted principle, the equation of the slow discharge theory has been derived for the conditions when several reacting particles participate in one slow step of complex stoichiometry. The experimental data for the kinetics of the electroreduction of anions BrO4? and BrO3? on the Hg-, Sb- and Bi-electrodes are in complete agreement with that equation. 相似文献

We present here the results of experiments measuring the energy spectra of electrons backscattered from massive homogeneous Al, Cu, Pd and W targets, with the probing beam primary energyE
0 varying from 4–32 keV. We have developed the electron backscattering theory based on solving the Boltzmann equation boundary problem by the invariant imbedding method and calculation of inelastic energy loss with the modified Landau function. Comparison of the calculated with experimental data shows that this expanded theory adequately describes the electron reflection processes. 相似文献

We presented the results of experimental study of electrical and luminescence properties of planar nanocomposites based on
gold island films and layers of efficient organic luminophores — aluminum (III) 8-hydroxyquinolinate (Alq3) and europium β-diketonates [Eu(DBM)3 bath, Eu(DBM)3 phen, and Eu(DBM)3]. The mechanisms of electroluminescence of such hybrid systems are discussed and the processes of luminescence excitation
in the organic component of nanocomposites are considered in detail. It is shown that the spectral characteristics of europium
β-diketonates are controlled by the Eu3+ ion fluorescence. The proposed mechanisms of nanocomposite electroluminescence are confirmed by the results of measurements
of cathodoluminescence spectra of organic luminophores. 相似文献
