Figure 4From: Investigations into the impact of various substrates and ZnO ultra thin seed layers prepared by atomic layer deposition on growth of ZnO nanowire arrayThe XRD spectra and ZNO peak ratios. (a) XRD spectra of NWs grown on pre-coated substrates with different thickness (from top to bottom, 2, 4, 6, 8, 10, 20, and 50 nm). (b) ZnO peak ratios for (1 0 1) to (0 0 2) as a function of substrate thickness.Back to article page
