A new method of theoretical investigation of the interdiffusion effect on electron states in quantum dots is proposed. The main point of the method is the replacement of the “veritable” confining potential formed due to the diffusion by a model potential, for which the Schrödinger equation solutions and the energy spectrum are known. In the framework of the proposed method we calculate the positions...
The electron-diffraction patterns from silicon with curved Kikuchi lines were obtained. It is revealed that curving of Kikuchi lines takes place simultaneously with the shift of point reflections from their normal positions. It is found that curving of Kikuchi lines is caused by limited defects in silicon crystals.
Calculation of the small-signal surface photoemf in MIS-structures has been performed. By assuming that under illumination the charge of the near-surface region of the semiconductor is constant, for the surface photoemf a simple formula is derived where the power of the incident light and the semiconductor parameters enter explicitly. It follows from the obtained expression for the limiting frequency...
Analysis of mechanical properties of polymer films is carried out for different ways of deformation including scaling and pulling off. An expression is obtained for the number of tractions, which may arise in a polymer film at various deformations.
A scheme of a three-block monolithic X-ray resonator with Si $$(04\bar 4,40\bar 4)$$ -configuration single crystal for NiKα2 and synchrotron radiation is proposed and realized experimentally. Specialties and advantages of the proposed scheme are given. It is shown that using asymmetric Bragg reflections makes possible to solve one of the basic problems of X-ray resonators, that of the input of...
Principles of development of the quantum theory of nonlinear processes on the basis of Lagrangian formulation are discussed. It is shown that in the framework of this formulation it is possible to preserve succession from the classical theory and, in particular, use these methods for studies of quantum systems. The quantum dispersion of a nonlinear oscillator excited by an external source and of a...
We study the equations of motion of a spherical oscillator model suggested by Bellucci and Nersessian, in the presence of a constant magnetic field. This model is shown to be exactly solvable classically in contrast to the Higgs oscillator which is not exactly solvable in magnetic fields.
Temperature dependences of thermoelectric parameters of the Pb0.22Sn0.78Te〈Ge(0.5 at%)〉 solid solution in the temperature range 140–440 K are investigated with the purpose to determine the perspectiveness of these solutions as a material for thermoelements.
The optical rectification of ultrashort laser pulses with a titled amplitude front in LiNbO3 crystal is studied theoretically. It is shown that the results of calculation are in reasonable agreement with experimental data.
