Microstructure Control and Crystallization Kinetics in Amorphous Cadmium-Germanium - Arsenide (Devitrification, Differential Scanning, Calorimetry)

CdGeAs(,2) is a member of the II-IV-V chalcopyrite semiconductor family. The crystallization of the amorphous form of this compound was investigated using Differential Scanning Calorimetry. The basic operating principles of the two currently most popular DSC instruments (the DuPont 1090 DSC and the Perkin-Elmer DSC7) in the context of glass crystallization kinetics are critically evaluated and compared. New analytical methods are introduced for the determination of kinetic parameters of crystallization, modeling to the Avrami and Arrhenius equations; and techniques for optimization of quantitative data from these devices is discussed for both heating rate and isothermal crystallization.
