Pulling long linear atomic chains from graphene: Molecular dynamics simulations

Abstract

Experimental methods for preparing long linear atomic chains from graphene and for using the chains to connect nanodevices are proposed based on classical and first-principles molecular dynamics simulations. We show that these methods are promising to pull out long monatomic chains, to dope other atoms, such as boron, nitrogen, silicon, and phosphorus in the chains, and to build the smallest and ultra-highly-integrated nanoelectron circuits in the near future.
