Abstract
A method and system for growing elongated crystalline materials. Crystalline melt rises through a capillary. At the upper end of the capillary is a die having a die tip. A seed crystal engages and draws the melt through the die tip. The die tip is characterized by a top surface and an aperture therein. The top surface is non-wetting with reference to the crystalline melt. The geometry of the aperture or inner edge defines the geometry of the crystalline filament formed.
