摘要：

Absorption, reflection, photoluminescence and magneto-absorption of MBE grown ZnSe heteroepitaxial layers and MQWs in ZnSySe1-y/Zn1-xCdxSe have been studied on etched from the substrate, deformation free, super-thin samples at T = 1.7 K and B less than or equal to 7.5 T. Analysis of oscillatory magneto-absorption spectra gives the possibility to establish a new set of ZnSe band parameters with a ''bare'' electron effective mass m(c)* = 0.123 m(0). Renormalization into a ''polaron'' set is necessary to describe exciton series. The combined use of these two sets permits us to obtain a good description of MQW excitonic spectra. The specific Fabry-Perot interference picture, characteristic for exciton-polariton phenomena, was observed in super-thin ZnSe samples.
