Figure 4From: Homoepitaxial regrowth habits of ZnO nanowire arrays Sample C. SEM images of ZnO NWs after the (a) first- and (b) second-time growths. Nanoantennas are observed. The inset in (b) is a zoomed-in image of a nanoantenna. (c) Bright-field TEM image of a nanoantenna and SAED patterns (inset) taken from tip, base, and junction areas. (d) High-resolution TEM image of the red-rectangular area in (c).Back to article page
