DETERMINATION OF THE ENERGY SPECTRUM OF A QUANTUM DOT BY THE METHOD OF OSCILLATORY REPRESENTATION

Abstract

ield is determined by the method of expression on an oscillator. The energy spectrum was calculated
taking into account the anharmonic correction for the parabolic confinement potential. For these conditions, an analysis of fluctuations in the energy spectrum was carried out. In strong magnetic fields, it
turns out that the hypothesis of the parabolic nature of the retention potential for two electronic systems
is quite plausible. The ability to control and control the properties of two-electron quantum dots, which
are a common representative of such a system, allows them to be used as a new element base for future
computers. Electronic systems with microparticles are of great interest both theoretically and experimentally. Today, despite the wide variety of semiconductor nanostructures for electronic devices, the process
of searching for a material with improved characteristics continues. The pace of use of nanomaterials in
industry is growing rapidly, which stimulates the development of synthesis methods to create new objects. The creation of new quantum-dimensional structures requires a clear understanding of the internal
structure of the quantum-mechanical processes taking place. In the course of the work, the energy spectrum of the quantum dot was calculated taking into account the anharmonic correction for the parabolic
confinement potential. To do this, an analysis of fluctuations in the energy spectrum was carried out. The
study of the energy spectrum of two electronic quantum dots in an external magnetic field allows you to
control the characteristics of a quantum dot.
