Abstract

We report remarkable changes in the magnetic properties of excitons as they acquire kinetic energy in wide (001) quantum wells of CdTe, ZnSe, ZnTe and GaAs. In particular, the magnetic moments (g-values) when magnetic fields are applied in the growth direction are shown to. have a strong dependence on the translational wavevector K-z. The dependence is particularly marked when Kz is of the order of the inverse of the exciton Bohr radius or, equivalently, when the translational kinetic energy becomes comparable with the exciton Rydberg. The behaviour is ascribed to motionally-induced mixing between the 1S hydrogenic exciton ground state and excited nP states and is describable by what appears to be a universal formula.
