Fundamentals of the CdTe synthesis

مفاهیم بنیادین سنتز CdTe

ABSTRACT

Different ways to achieve liquid, vapour, solution or even solid synthesis of CdTe are examined from a thermodynamic viewpoint. The catalytic character of the reactions of formation is stressed. The advantages of solution synthesis, mainly using the so-called Cold Travelling Heater Method (CTHM), are shown. Several kilograms of material in a run can be produced by this safe, non-expensive process, which can be easily extended to the production of homogeneous CdZnTe. Purity, homogeneity and possibility to obtain a composition corresponding to the congruent sublimation line are among the assets of this technique.
