High temperature Hall-effect investigations were used to study the change of the concentration and mobility of charge-carriers in Cd0.85Mn0.10Zn0.05Te and Cd0.85Mn0.10Zn0.05Te: In crystals grown by the vertical Bridgman technique. The Cd0.85Mn0.10Zn0.05Te and Cd0.85Mn0.10Zn0.05Te: In samples are characterized by optical and electrical measurements, and by IR-microscopy. We determined that the value of band gap increase with the Mn and Zn amount increasing in the Cd1-x-yMnxZnyTe crystals. We also show that after the high-temperature Hall-effect measurements performed under Cd overpressure the both crystals resistivity increase from 104 Ohm×cm to 106 Ohm×cm, and amount and size of Te inclusions decrease. According to the results of the high temperature Hall-effect investigations the temperatures and Cd vapor pressures intervals were established in which Indium plays major role and controls the concentration of charge carriers. |
