Physical and Electrical Performance of Vapor-Solid Grown ZnO Straight Nanowires.
Physical and electrical properties of wurtzitic ZnO straight nanowires grown via a vapor-solid mechanism were investigated. Raman spectrum shows four first-order phonon frequencies and a second-order Raman frequency of the ZnO nanowires. Electrical and photoconductive performance of individual ZnO straight nanowire devices was studied. The results indicate that the nanowires reported here are n-type semi-conductors and UV light sensitive, and a desirable candidate for fabricating UV light nanosensors and other applications.
