Abstract
ZnO nanostructures are of grand attention in electronic devices, due to their notable optoelectronic behavior. Colloidal synthesis was assisted to produce a variety of ZnO nanostructures. The ZnO nanostructures were studied with XRD, which showed the hexagonal wurtzite structure. FESEM images were helped to study the size and shape of the ZnO nanostructures. The synthesized nanostructures were varied in their size and shape, which was identified from FESEM images. UV-Visible absorption spectra have showed the Characteristic band edge absorption of ZnO. Further ZnO nanostructures/p-Si heterojunction diodes were fabricated using spray technique. We observed good rectifying behavior in the I-V characteristics of the fabricated p-n junction diode. The diode characteristics reveal that the fabricated p-n junction diode plays a suitable role in the field of nanoelectronics.
