Abstract

The selective regrowth of GaN during sidewall-seeded epitaxial lateral overgrowth was performed. In addition to adjusting the V/III ratio, control of offset angle of the sidewall was found to be effective for realizing one-sidewall-seeded a-plane (1 1 2̄ 0) GaN on r-plane (1 1̄ 0 2) sapphire. The number of coalescence regions on the grooves was reduced, and threading-dislocation and stacking-fault densities as low as 106-107 cm-2 and 103-104 cm-1, respectively, were successfully realized. © 2009 Elsevier B.V.
