Surface reconstruction of ZnO nanowire arrays via solvent-evaporation-induced self-assembly
Vertically aligned ZnO nanowires (NWs) can be reconstructed on large scales by a solvent-evaporationinduced method. The morphologies of the nanowires are regulated by changing the concentration of the solution. Possible mechanism, which the compressive residual stresses and wires/wires self-attraction can be responsible for the surface reconstruction, is addressed. Furthermore, we compare the structural properties of ZnO nanowires before and after reconstructed. (C) 2010 Elsevier B.V. All rights reserved.
