MNTE FRACTIONAL MONOLAYERS IN CDTE CDMGTE HETEROSTRUCTURES - A COMPARATIVE-STUDY OF MAGNETIC POLARONS/

By performing selective excitation of the exciton luminescence on two- dimensional digital magnetic heterostructures based on II-VI semicondu ctor materials, we have studied the influence of electronic confinemen t and of exciton primary localization on the formation of exciton magn etic polarons. The digital distribution of the magnetic layers has bee n confirmed by transmission electron microscopy and the shift between the energy of selective excitation and conventional luminescence peak positions has been attributed to the formation of magnetic polarons.
