Two-step selective epitaxy (SAG/ELO) of (11 (2) over bar2)GaN on (113)Si substrate is studied to reduce the defect density in the epitaxial lateral overgrowth. The first SAG/ELO is to prepare a (11 (2) over bar2)GaN template on a (113)Si and the second SAG/ELO is to get a uniform (11 (2) over bar2)GaN. It is found that the reduction of the defect density is improved by optimizing the mask configuration in the second SAG/ELO. The minimum dark spot density obtained is 3 x 10(7)/cm(2), which is two orders of magnitude lower than that found in a (0001)GaN grown on (111)Si. (C) 2009 Elsevier B.V. All rights reserved.
