The effect of the pressure difference across the free surface on the static meniscus shape in the case of ribbon growth by edge-defined film-fed growth (E.F.G.) method

In this paper explicit formulas, prescribing pressure difference limits, are reported in the case of ribbon growth by edge-defined film-fed growth method. These formulas were established in general for any growth configuration and for materials for which αc+αg<π/2. The limits represent the boundaries of the ranges where the pressure difference value has to be chosen or can be chosen, in order to have a static and stable convex free surface. The advantage of this kind of formulas is that they can be used in the experiment or in the manufacturing technology design.
