Figure 2From: Large-scale and uniform preparation of pure-phase wurtzite GaAs NWs on non-crystalline substratesXRD pattern of GaAs NWs and the TEM images of the corresponding SAED pattern. (a) XRD pattern of GaAs NWs grown by 0.1-nm thick Au film on SiO2/Si substrates showing the wurtzite structure; (b) and (c) are the TEM images (scale bar = 50 nm) and the corresponding SAED pattern of one typical NW showing the WZ phase and growth orientation of <11 2 ¯ 2>.Back to article page
