Abstract

A string for growing ribbon crystal has a core and an outer cover, the cover composed of at least two different materials, chosen with the material of the core in amount and kind such that the CTE of the covered core matches in net, that of the silicon ribbon. The cover material is also chosen so that silicon readily wets significantly around the string, subtending an angle of at least about 55 degrees, up to a fully wetted string, resulting in a relatively thick strong ribbon adjacent the string, closer in thickness to the diameter of the sting. This prevents a thin, fragile ribbon near the string. For silicon ribbon, a cover may be an interspersed composition that is predominantly of silica, with some SiC. The core may also be composed of silica and SiC, in different proportions, and different geometry, or may be a single material, such as Carbon.
