Magneto-photoluminescence of GaAs/AlGaAs heterojunctions under hydrostatic pressure

We report measurements of photoluminescence of GaAs/AlGaAs heterojunctions using hydrostatic pressure to reduce the Zeeman energy. A red-shift is observed near nu = 1 which falls with pressure, consistent with theoretical predictions of Skyrmionic exciton recombination energies. When the Zeeman ener...

Description
Summary:We report measurements of photoluminescence of GaAs/AlGaAs heterojunctions using hydrostatic pressure to reduce the Zeeman energy. A red-shift is observed near nu = 1 which falls with pressure, consistent with theoretical predictions of Skyrmionic exciton recombination energies. When the Zeeman energy is reduced below a critical value the redshift vanishes. (C) 1998 Elsevier Science B.V. All rights reserved.
