Abstract

Properties of a two-dimensional electron gas with a density of 5 × 10¹¹ cm^-2 in a ZnSe/(Zn,Be,Mg)Se quantum well structure have been investigated by means of polarized magneto-luminescence in fields up to 47 T and by an optically detected resonance (ODR) technique. With increasing magnetic field, the optical spectra of the electronic system changes its appearance from Landau-level-like with a linear shift of lines, to excitonic-like with a diamagnetic shift. The transition occurs at filling factor 2. Pronounced oscillatory features at even filling factors are found for the luminescence intensity and polarization degree, the energy of optical transitions, and in ODR signal.
