Zinc Oxide Microstructures: Zinc Oxide Microtowers by Vapor Phase Homoepitaxial Regrowth (Adv. Mater. 8/2009)

Simultaneous axial and radial epitaxies can be achieved by growing ZnO microtowers by repeating a growth cycle several times, report Zhengwei Pan and co-workers on p. 890. The as-grown ZnO microtowers display a preferential growth habit of hexagonal prism–dihexagonal pyramid. Some rare or new growth habits such as dihexagonal prism–dihexagonal pyramid, hexagonal prism–trihexagonal pyramid and dihexagonal prism–trihexagonal pyramid (as shown on the cover) have also been identified.
