RESEARCH ON THE INFLUENCE OF THE GEOMETRY OF A QUANTUM MOLECULE ON ELECTRONIC STATIONARY STATES

The work is devoted to the study of a quantum molecule formed from three spherical quantum dots placed along one straight line. The geometry of a linear quantum molecule formed from three spherical nanocrystals is analyzed. Four placement cases are selected for the study. A dispersion equation is obtained for the study of the energy spectrum of an electron in a linear QM from three spherical QDs. The influence of the distance between the QDs and the QD size on the energy spectrum in a symmetric QD was analyzed. The finite element method was used for comparison, which confirmed the qualitative picture of the results and made it possible to analyze the probability density and the probability of an electron being in a linear QD. The results show that it is possible to control the location of an electron by giving it certain energy values.
