Growth of Uniformly Aligned ZnO Nanowire Heterojunction Arrays on GaN, AlN, and Al<sub>0.5</sub>Ga<sub>0.5</sub>N Substrates
Vertically aligned single-crystal ZnO nanorods have been successfully fabricated on semiconducting GaN, Al0.5Ga0.5N, and AlN substrates through a vapor-liquid-solid process. Nea...
