Figure 5From: Arc Discharge Synthesis and Photoluminescence of 3D Feather-like AlN NanostructuresA scheme of the alternate growth mechanism. n → 1 is the direction perpendicular to (10 1 ¯ 3) and n → 0 is perpendicular to (0001). The theoretical angle (α1,2,3) between the trunk and its branches is 31.65°.Back to article page
