In modulation-doped ZnSe/(Zn,Mg)(S,Se) quantum well structures with electron concentration of about 10 11 cm --2 a new resonant optical transition involving four particles (one hole and three electrons) was found in external magnetic fields in photoluminescence excitation and reflectivity spectra.

The luminescence of n-type modulation doped GaAs/GaAlAs single quantum well structures has been used to probe the relaxation processes in the presence of quasi two dimensional electron gas under high magnetic fields. It was found that the magnetic field induced modulation of the Landau levels separa
