Query: Optical properties and single-electron states of the nanosystem that
  contains three quantum dots   The quantum molecule consisting of three quantum dots that forms a triangle
with its centers is studied. The electron wave function in the nanosystem is
written using the linear combination of orbital quantum wells. The dispersion
equation for numerical calculations of the electron stationary states in a
quantum molecule is found. A numerical calculation of the electron energy
spectrum in the molecule formed by three quantum dots of a spherical shape is
carried out. The influence of the nanocrystal size, the distance between them
and the symmetry of the quantum molecule on the electron energy spectrum is
studied. The cases of symmetry of an equilateral and an isosceles triangle are
considered.
