我们报道了三维（3D）纳米多孔石墨烯，具有保留的二维电子特性，可调节的孔径，以及用于电子应用的高电子迁移率。由相互连接的石墨烯组成的复杂3D网络保留了无质量狄拉克费米子的二维相干电子系统。纳米多孔石墨烯的输运性质表现出半导体性质和强的孔径依赖性，以及独特的角度独立性。独立的、具有二维电子特性和高电子迁移率的大规模纳米多孔石墨烯在三维电子器件的实际应用中具有很大的前景。
We report three-dimensional (3D) nanoporous graphene with preserved 2D electronic properties, tunable pore sizes, and high electron mobility for electronic applications. The complex 3D network comprised of interconnected graphene retains a 2D coherent electron system of massless Dirac fermions. The transport properties of the nanoporous graphene show a semiconducting behavior and strong pore-size dependence, together with unique angular independence. The free-standing, large-scale nanoporous graphene with 2D electronic properties and high electron mobility holds great promise for practical applications in 3D electronic devices.
