Abstract

In this work, we synthesized Cu-doped ZnO nanowires through a vapor–liquid–solid process. We investigated their composition and photoluminescence properties; and we found the Cu-doped ZnO nanowires have a c-axis preferential growth direction, uniform Cu distribution and a characteristic spectrum. We further investigated their electrical property by fabricating a simple field effect transistor based on an individual C-shaped Cu-doped ZnO nanowire. The electrical studies reveal that the Cu-doped ZnO nanowire has n-type conductivity and ultralow electron mobility.
