Excitonic structure in a quantum well under the tilted magnetic field

By using an appropriate coordinate transform we have calculated variational ly the ground state exciton binding energy in the single square well under the tilted magnetic field. The dependence of the binding energy to the magn etic field strength, well width, and the direction of the field is discusse d. We conclude that for small well widths the exciton binding energy is ver y sensitive to the tilt angle. (C) 2000 American Institute of Physics. [S00 21-8979(00)05517-1].
