Abstracts

EN

The light emitting devices based on the p-Zn_{1-x}Mn_{x}Te bicrystals have been fabricated. The Zn_{1-x}Mn_{x}Te devices produce red and green emission originating from the internal d-shell transitions in the Mn^{2+} ions and the donor-acceptor pairs recombination, respectively. A critical behavior of the magnetic field dependence of the green emission intensity and a positive magnetoresistance near the Curie-Weiss temperature in the Zn_{1-x}Mn_{x}Te devices was observed.
