Figure 1
A schematic of the atomic sites for interstitial H in GaN (Park & Chang, 2012). Gray circles represent Ga atoms, white circles represent N atoms, the patterned circle represents an Mg atom and black circles represent H atoms. AB, BC and OA indicate antibonding, bond-centered and off-axis antibonding sites, respectively. These sites have two types of orientation: parallel (∥) or perpendicular () to the c axis. |
