Growth of planar reduced dislocation density m-plane gallium nitride by hydride vapor phase epitaxy

摘要

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.
