Abstract

In regard to the high transparency and superior electrical conductivity of thin-film transparent conductive oxides in applications such as transistors using a simple surface patterning and dip-casting process, the Ga-Zn system is very interesting. In this study, the density, surface tension and viscosity of liquid Ga-Zn alloys were measured using the discharge crucible method (DC). The obtained temperature dependency of physicochemical properties of Ga-Zn alloys were determined in the range of 323–823 K. The surface tension, viscosity and density of Ga-Zn alloys across a wide range of temperatures increased with increasing Zn content in the alloy. The obtained experimental results were compared with the Quasi Chemical Model for regular solutions (QCA) and Butler models for surface tension, and with several models for viscosity.
