Single crystal growth and properties of the γ-phase in the CuInSe2–2CdTe system

Abstract: The intermediate solid solution, abbreviated as the γ-phase, exists within the CuInSe2 –2CdTe system. It has a wide homogeneity range and can be considered as a continuous solid solution between the high-temperature (HT) modification of CuInSe2 and CdTe. Single crystals of the γ-phase are grown by a modified Bridgman method. Their crystal structure and electrical properties are studied. The γ-phase crystals crystallize in the cubic structure of zinc blende (space group ) and possess intrinsic p-type conductivity with hole mobilities up to 8.29cm2/Vs. [Copyright &y& Elsevier]
