摘要

研究了一种用BaO纳米粒子修饰还原氧化石墨烯和单壁碳纳米管的杂化纳米结构的技术。利用量子方法数值建立了杂化纳米结构功函数减小的规律。与常规样品相比，功能化杂化纳米结构的发射电流增加了40倍以上。这种混合纳米结构对于电流密度至少为2 a /cm2的器件可能很有希望。

Functionalization of Graphene-Nanotube Nanostructures by BaO Nanoparticles for Field Emission Devices

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.
