Possible Ferro-electro-magnetic performance of “reduced graphene oxide” deposited on “ZnO-nanorod (NR) decorated with nanocrystalline (nc) Au particles”

Abstract

Possible ferro-electromagnetic performance of “reduced graphene oxide (r-GO)” deposited on the surface of “ZnO-nanorod (NR) decorated with nanocrystalline (nc) Au particles” is studied using different spectroscopies and magnetic measurements. The presence of carbon/zinc-interstitials (Zni), nc-Au, and oxygen vacancies are established through electronic property studies using different spectroscopic measurements. The magnetic moment (M) applied magnetic field (H) curve and electrical measurement current (I)–voltage (V) loops show that nc-Au/ZnO-NRs:r-GO is ferromagnetic and partial ferroelectric, respectively. The work functions are obtained from the lower kinetic energy of ultraviolet photoelectron spectroscopy, which is correlated with the enhancement of ferro-electro-magnetic performance. Both ferroelectric and ferromagnetic performance of nc-Au/ZnO-NRs:r-GO nanocomposite material could be useful for ferro-electro-magnetic technological applications.
