CRYSTALLINE COMPOSITION, WAFER, DEVICE, AND ASSOCIATED METHOD

摘要

A crystalline composition is provided that includes gallium and nitrogen. The crystalline composition may have an amount of oxygen present in a concentration of less than about 3x10¹⁸ per cubic centimeter, and may be free of two-dimensional planar boundary defects in a determined volume of the crystalline composition. The volume may have at least one dimension that is about 2.75 millimeters or greater, and the volume may have a one-dimensional linear defect dislocation density of less than about 10,000 per square centimeter.
