Functionalization of Graphene-Nanotube Nanostructures by BaO Nanoparticles for Field Emission Devices
摘要
Abstract
A technology for the functionalization of hybrid nanostructures made of reduced graphene oxide and single-wall carbon nanotubes with BaO nanoparticles is developed. Quantum methods are used to numerically establish the regularities of reducing the work function of hybrid nanostructures. An increase in the emission current of the functionalized hybrid nanostructures by more than 40 times compared to conventional samples is established. Such hybrid nanostructures may be promising for devices with a current density of at least 2 A/cm2.
