| The light emitting devices based on the p-Zn1-xMnxTe bicrystals have been fabricated. The Zn1-xMnxTe devices produce red and green emission originating from the internal d-shell transitions in the Mn2+ 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 Zn1-xMnxTe devices was observed. |
