چکیده
Thermodynamic analysis and characterization of the investigated Ga-Ge-Sb alloys, which is of a practical importance in electric semiconductors industry, are presented in this paper. Thermodynamic analysis are done by the used of experimental investigation technique of Oelsen calorimetry and different thermal analysis (DTA) and thermodynamic predicting methods, while characterizations are done by the used of SEM-EDX analysis. The experimental and calculated values are shown a good agreement as well as the obtained phase diagram of the investigated semiconductor alloys.
