Abstract
We report on low-defect-density non-polar a-plane and m-plane GaN films grown by sidewall epitaxial lateral overgrowth (SELO) technique. Dislocations and stacking faults were decreased markedly over the whole area, and surface roughness was decreased with decreasing defect density. The photoluminescence intensity of SELO a-plane and m-plane GaN was about 200 times higher than that of a-plane and m-plane GaN template. We also fabricated and characterized LEDs on a-plane and m-plane GaN using SELO technique. The light power of LEDs increased with decreasing of threading dislocation.
