Abstract
The ZnO microrafts with diamond-shaped cross sections have been prepared by the vapourtransport method in air using a copper catalyst. Our results showed that the backbone ofthese microstructures had a quadrate cross section growing along the direction, while its diamond-shaped branches were growing along the [0001] direction. Thecopper-doped structures exhibited modified Raman and photoluminescence spectra andwere ferromagnetic at room temperature. The possible growth process of thesemicrostructures is discussed.
