THERMODINAMICS AND THERMOPHYSICAL PROPERTIES OF LIQUID Si-Te ALLOYS

Thermophysical properties of liquid Si-Te alloys are interesting for electronic industry. However, despite the importance of these properties, the determination of their thermophysical properties is often lacking due to the experimental difficulties related to high melting temperatures. Therefore, it is possible to estimate the missing values by using theoretical models. The energetics of mixing in liquid Si-Te system has been analyzed through the study of the concentration dependence of various thermodynamic, surface (surface tension and surface composition) and structural properties (concentration fluctuations in the long-wavelength limit and chemical short-range order parameter) in the framework of the Compound Formation Model (CFM) and Quasi Chemical Approximation for regular solutions (QCA), and subsequently were compared with the data available in literature.
