Figure 1From: Large-scale and uniform preparation of pure-phase wurtzite GaAs NWs on non-crystalline substratesSEM and TEM images depict the surface morphology of GaAs NWs. (a) SEM image (scale bar = 2 μm) and magnified image in the inset (scale bar = 100 nm) and (b) TEM image (scale bar = 100 nm) of GaAs NWs grown by 0.1-nm thick Au film. (c) NW diameter distribution statistics performed in (b) is plotted after a measurement of approximately 100 NWs in TEM images.Back to article page
