ZnO Nanowires for LED and Field Emission Displays
We report the use of ZnO nanostnictures in various display applications. Single-crystalline, vertically oriented nanowires with typical diameters of 100 nm and a length of 1 -2 μm were grown at deposition temperatures below 100℃. Homogeneous growth over areas up to 50 cm2 on Si as well as on various metallic, transparent and flexible substrates were obtained. Visible electroluminescence in the region between 400 and 900 nm and narrow-line near-ultraviolet electroluminescence is demonstrated. The physical conditions leading to single-crystalline growth at low temperature, the role of defects, and the possibility of doping are discussed. These issues present the main challenges on the road towards high emission rates in LED operation. Under certain conditions sharply tipped wires can be grown that hold promise for field emission applications.
