Figure 2From: Fabrication of vertical GaN/InGaN heterostructure nanowires using Ni-Au bi-metal catalystsA typical TEM image. (a) Low-magnitude TEM image and (b) HRTEM image of a GaN nanowire grown by Au/Ni catalysts. The inset SAED pattern in (b) shows that the direction of GaN nanowire was [0001].Back to article page
