✦ Synopsis

The procedure of self-consistent calculation of excitonic states in T-shaped quantum wires is developed. The part of the exciton wave function describing an electron motion in the plane perpendicular to the wire direction and a term describing motion of a hole and the relative electron-hole motion in the wire direction are proposed to be determined self-consistently. Importance of this self-consistent approach is discussed. In the case of quantum wires made of diluted magnetic semiconductors the calculations indicate that there is existence of the additional source of the magnetic field dependence of exciton binding energy, due to p-d exchange interaction.
