Patent ID: 8728236

Claim:
A single crystal III-V nitride material having a large area of greater than 2 cm 2 on a face thereof and having a uniformly low dislocation density not exceeding 3×10 6 dislocation per cm 2 of growth surface area on the face, and including within the single crystal III-V nitride material adjacent to the face a plurality of filled pits, wherein each filled pit has a pit size embodying a maximum diameter or transverse dimension parallel to the plane of the growth surface, and the filled pits have an average pit size of greater than 25 microns, wherein the filled pits are present within the single crystal III-V nitride material at a concentration of at least 100 filled pits per square centimeter of the growth surface area; and wherein the face has a density of unfilled pits not exceeding 3 pits/cm 2 of growth surface area.
