Ma?hanets %J Semiconductor Physics, Quantum Electronics & Optoelectronics %T Electron, hole, and exciton spectra in a quantum wire crossing the quantum well %X The electron, hole, and exciton energy spectra are calculated within the effective mass and rectangular potential approximations for a combined semiconductor nanoheterosystem consisting of a cylindrical semiconductor quantum wire crossing the plane quantum well. It is shown that the electron (hole) in such a system is characterized by five quantum numbers related to five degrees of freedom for a quasiparticle. The dependences of the quasiparticle energy on the quantum wire radius and the quantum well width are researched. %N 3 %K quantum wire, quantum well, quantum dot, energy spectrum %P 51-57 %V 10 %D 2007 %L zu26586
