An investigation into the effects of applied magnetic field during Zn vacuum thermal evaporation on ZnO nanostructures

Zno nanostructures were produced with an innovative and simple vacuum thermal evaporation method with evaporating zn in the presence of strong static electric and magnetic fields perpendicular to each other. these evaporated zn thin films were oxidized on the furnace to obtain zno. in order to investigate the effects of magnetic field on zno nanostructures in this method, two different setups with different magnetic field strengths were assembled. morphology and structure of zno thin films in both setups were investigated by micrographs prepared by field emission scanning electron microscopy (fesem) and x-ray diffraction (xrd) analysis. results showed that the grown nano rods of zno in both setups were blade-like and match-like. increase in magnetic field changed the dominant type of nano rods from blade-like in weaker magnetic field to match-like in stronger magnetic field. also, increasing magnetic field strength caused different crystalline orientation in zno nanostructures. the results suggested that morphology and structure of zno thin films were affected by applying magnetic fields with different strengths during deposition of zn in this innovative method.
