Crystal growth of ternary phases with homogeneity range: Modeling and experiments

  • Synthesizing crystals of ternary solid solutions M2Q3 (M=Bi, Q=Se, Te) with definite composition requires advanced knowledge on the phase relations in the system. By chemical vapor transport [1] the request of homogeneous crystallization can be fulfilled. The experimental scope gets supported by modeling. A phase diagram of the pseudobinary system generated with FactSage [2] (Fig. 1) provides the thermodynamic parameters of the miscibility gap respectively the solid solution. Additionally, these parameters are used to optimize the processes while chemical vapor transport with iodine [3]. The optimum transport conditions of ϑsource = 500 °C and ϑsink = 450 °C has been applied as for the synthesis of the binary compounds [4]. Both by modeling and experiments the congruent transport can be demonstrated, Fig. 2.
