Abstract:
Zn 0.5 Mn 0.5 Te and Zn 0.5 Mg 0.5 Te:Co 2+ single crystals were grown by chemical transport reaction (CTR) method which is applied to the temperature modulation method. The energy gaps of the grown single crystals at 298 K are 2.340 eV for Zn 0.5 Mg 0.5 Te and 2.213 eV for Zn 0.5 Mg 0.5 Te:Co 2+ . The temperature dependence of the energy gap is well represented by the Varshni equation. Impurity optical absorption of Zn 0.5 Mg 0.5 Te:Co 2+ single crystal is described by the electronic transitions between energy levels of Co 2+ ion which is sited at T d symmetry point in the crystal.
