The growth and characterization of Zn nanowires covered with ZnO using plasma-assisted molecular beam irradiation

The Zn nanowires covered with ZnO were grown by oxygen plasma-assisted molecular beam irradiation method and characterized, was reported. To grow these nanowires, oxygen plasma was irradiated to Zn thin film evaporated on Si(100) substrate. Scanning electron microscopy and transmission electron microscopy observation results of nanowires revealed that the nanowire has diameter of 80 nm, and nanowires was constructed with crystalline ZnO. Moreover NWs surface was covered by crystalline ZnO. Further Zn and ZnO orientation was coincident and resulted the ZnO appeared by oxidation of Zn nanowires.
