Abstract
The present invention includes methods of promoting single crystal growth via solid-solid transformation of an appropriate glass, while avoiding the gaseous or liquid phase. In certain embodiments, in the all-solid-state glass-to-crystal transformation of the invention, extraneous nucleation is avoided relative to crystal growth via spatially localized laser heating and optional inclusion of a suitable glass former in the composition. The ability to fabricate patterned single-crystal architecture on a glass surface was demonstrated, providing a new class of micro-structured substrate for low cost epitaxial growth and active planar devices, for example.
