Abstract

Energy shifts of the higher states of 2D excitons in a GaAs(265 Å)/AlAs(250 Å) Multi-Quantum-Well (MQW) under high magnetic fields up to 23 T were observed clearly with photoluminescence excitation spectroscopy (PLE) in the photon energy region of 1.52 eV up to 1.55 eV. The H3(1s)-assigned line was split into 3 lines over 18 T. The crossing behavior between the ground state of a heavy-hole exciton (HH1(1s)) and the ground state of a light-hole exciton (LH1(1s)) was also observed around 15 T.
