| Abstract: | Atomic and electronic properties of N-N split interstitial in GaN nanowires have been investigated using first principles calculations. The formation energy calculations show that the N-N interstitial favors substituting an N atom at the surface of the nanowires. The interstitial induces localized states in the band gap of GaN nanowires. |
