Tilted Epitaxial ZnO Nanospears on Si(001) by Chemical Bath Deposition

Abstract

We show that epitaxial ZnO nanospears can be deposited onto degenerate p-type Si(001) from an alkaline supersaturated solution of Zn(II) at 70 °C using chemical bath deposition. The lattice mismatch between the hexagonal ZnO and-diamond cubic Si is reduced from -40.16% for an un-tilted structure to -0.25% in the ZnO[1210] direction and -0.99% in ZnO[2576] direction by tilting the nanospears 51° relative to the surface normal. The tilted nanostructure brings the (2023) planes of ZnO into coincidence with the (001) planes of Si. © 2009 American Chemical Society.
