Abstract

SnO₂-RGO nanocomposite has been synthesized by thermal evaporation method in a single step and its field emission (FE) properties are investigated. at the base pressure 1×10^-8 mbar is reported. Prior to the FE studies, the synthesized SnO₂-RGO nanocomposite is characterized using XRD, SEM and TEM to reveal its structural properties. The SnO₂-RGO nanocomposite emitter is found to deliver a current density ~100 μA/cm² at an applied electric field of ~9.2 V/μm. Moreover, the nanocomposite shows fairly good emission stability without significant degradation of emission current. The FE results seem to be encouraging, indicative of potential candidature of the SnO₂-RGO nanocomposite emitter as an electron source for practical applications in vacuum nanoelectronic devices, upon further optimization of morphology.
