Figure 12From: Tuning of structural, optical, and magnetic properties of ultrathin and thin ZnO nanowire arrays for nano device applicationsAtomic arrangement, interface interaction, and O 2 diffusion mechanism. (a) Atomic arrangement within ZnO NWs and interface interaction with Cu substrate. (b) O2 diffusion mechanism to the Cu substrate due to shift in bond alignment and reconstruction of bonds after UHV thermal annealing treatment.Back to article page
