Temperature dependence of critical supersaturation and interfacial tensions in In-P binary solutions

Abstract

The critical supersaturation temperature in In-P binary solution was determined by the liquid phase epitaxial growth technique in the temperature range 570–750°C. Using the step-cooling method, the experimental values of the critical supersaturation temperature decreases from 31 to 10°C with increasing temperature. According to the classical homogeneous nucleation theory, the interfacial tensions between the solid and the liquid were estimated as a function of temperature. It was found that the interfacial tension tends to fall as the temperature increases.
