Abstract
ZnO nanorod arrays can be synthesized by a seed-assisted chemical reaction under ultrasonic spray pyrolysis. Several semiconductor oxides including n and p type can be composed outside of ZnO nanorod. The “oriented attachment” and “self-assembly” crystal growth mechanisms were proposed to explain the formation of the ZnO/MO (M=Fe, Sn, Cu, Ni) nanostructures. Sensors based on the ZnO/MO heterojunction nanostructure were fabricated and investigated for their gas sensing properties.
