Abstract
  • We study the photoluminescence from the negatively charged (X-) trions and neutral (X) excitons, in a diluted 2DEG in a magnetic field (B) up to 55 T. At zero B we analyze the evolution of the X- and X emission intensity, tuning it through the optical depletion effect. At non-zero field we find that the emission intensity of the singlet state of the trion and of X are in inverse proposition to B, revealing the effect and the mechanism of the magnetic confinement of and of the excitonic shrinkage on the emission intensity.
