Abstract
A method of growing highly planar, fully transparent and specular m-plane gallium nitride (GaN) films. The method provides for a significant reduction in structural defect densities via a lateral overgrowth technique. High quality, uniform, thick m-plane GaN films are produced for use as substrates for polarization-free device growth.

7. An m-plane III-nitride lateral growth comprising a coalesced film that has lower dislocation densities in overgrown regions due to blocking or bending of dislocations through lateral growth.
- 8. A III-nitride film having a top surface with a non-polar orientation.

13. A method of growing non-polar III-nitride, comprising:
(a) performing a lateral epitaxial overgrowth (LEO) of the III-nitride from a surface resulting in a top surface that is a non-polar III-nitride. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
