Paper Abstract

Photoluminescence spectra of modulation-doped quantum well structures based on II-VI semiconductors (CdTe/CdMgTe and ZnSe/ZnBeMgSe) were studied in high magnetic fields it the range of 2D electron concentrations of (1-5)x1011 cm-2. The following peculiarities were found at low mangetic fields: (1) linear increase of the photoluminescence energy with increasing magnetic fields, (2) jumps in this dependence at integer filling-factors, (3) periodical changing of Zeeman splitting. The observed behavior are interpreted in a frame of a model which takes into account combined exciton electron recombination processes in the presence of magnetic fields.
