High-index facets bound ripple-like ZnO nanobelts grown by chemical vapor deposition
Abstract
Single-crystal ripple-like ZnO nanobelts (NBs) were formed spontaneously in a chemical vapor deposition process. Part of the ZnO NBs exhibits ripple-like structure and “propagates” along the growth direction of the ZnO NBs. The flat side-facets of the ripple-like structures are close to the high-index facets of and the major surfaces of such ripple-like structure belong to the {20} planes.
