The properties of electron and hole spectra in a quantum wire crossing plane quantum well in external medium

The electron and hole energy spectra in the combined semiconductor nanoheterosystem consisting of cylindrical
semiconductor quantum wire perpendicularly crossing the plane quantum well placed into the external medium
are calculated within the e�ective mass approximation and rectangular potential method. The dependences of
quasiparticles energies on the radius of quantum wire and width of the quantum well are studied in detail.
