Abstract :
The spectral characteristics of exciton in combined nanoheterosystem consisting of semiconductor cylindrical quantum wire containing two quantum dots separated by thin barrier-shell are investigated. It is shown that the binding energy non monotonously depends on the geometrical characteristics of nanoheterosystem approaching several minimum and maximum magnitudes.
