XRD 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 <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/632/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/632/mathml/M2">View MathML</a>2>.
