摘要：
Reflectivity, photoluminescence and photoluminescence excitation spectra have been studied in modulation-doped CdTe/CdMgTe quantum well structures containing a 2DEG of low density. Optical transitions related to the creation of excitons. bound exciton-electron complexes (trions) and exciton cyclotron resonance (ExCR) states have been found. The modification of the high energy tail on the exciton absorption line into several discrete ExCR lines was observed in magnetic fields.
