Paper Abstract

Strict process control, combined with proprietary process enhancements have enabled the production of large-scale single-crystal sapphire that demonstrates crystalline quality in excess of what has previously been possible. Extremely low defect densities, narrow rocking-curves, and very low stress gradients in the material are demonstrated through various X-ray diffraction techniques.
