The Seebeck coefficient of the solid and liquid germanium.

The knowledge of the Seebeck coefficient of materials is essential in determining the actual solid/liquid interface temperature during the melt growth of crystals. In this study, the Seebeck coefficient of the solid and liquid germanium was measured employing the small ?Ttechnique. The Seebeck coefficient increased from -107 µ V/°C at 857°C to -54 µ V/°C at 931°C in the solid. However, an average constant value of -0.6 µ V/°C was obtained in the liquid from 938 to 960°C, above which a value of -18 µ V/°C was recorded. Also, when the liquid samples were cooled below the melting point, a melt supercooling was observed, which seemed to be larger with higher melt temperatures. [ABSTRACT FROM AUTHOR]
