Filling-factor dependence of magneto-luminescence in IT-VT QWs with 2DEG

Conference ·
OSTI ID:976402

Photoluminescence spectra of modulation-doped quantum well structures based on IT--VT semiconductors (CdTe/CdMgTe and ZnSe/ZnBeMgSe) were studied in high magnetic fields it the range of 2D electron concentrations of (1 --5) x 1011 cm2. The following peculiarities were found at low magnetic fields: (i) linear increase of the photoluminescence energy with increasing magnetic fields, (ii) jumps in this dependence at integer filling-factors, (iii) 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.
