We investigate the existence of a band structure in GaAs/AlxGa1-x
superlattices with cylindrical symmetry, namely GaAs/AlxGa1-xAs
cylindrical superwires. These systems consists of a large number of
concentric GaAs and AlxGa1-xAs alternate cylindrical shells around a
central GaAs cylindrical wire. Despite the radial configuration (that
breaks the translational symmetry) and the electron confinement in the
central three-dimensional well, a band structure can emerge depending on
the number and thickness of the cylindrical shells. (C) 1999 Academic
