The meniscus in Czochralski growth

The observation by Antonov [Sb. Rost Kristallov 6 (1965) 158, translated in Growth of Crystals, Consultants BureaU, 1968] that the meniscus of a germanium crystal, growing by the Czochralski process, is inclined at 10–20° to the vertical at the solid-liquid interface is explained using thermodynamic theory of surfaces. The effect is shown to imply that molten germanium does not completely wet its own solid and the average value of the surface free energy of solid germanium at its melting point is estimated to be about 740 erg cm-2.
