It is the first to identify two types of NFE states in graphane nanoribbon superlattices and explore their modulation through electron doping.
Findings
Two types of NFE states identified in graphane nanoribbons.
Electron doping can open vacuum transport channels.
NFE states are similar to those in graphene and boron nitride nanoribbons.
Abstract
Nearly free electron (NFE) state has been widely studied in low dimensional systems. Based on first-principles calculations, we identify two types of NFE states in graphane nanoribbon superlattice, similar to those of graphene nanoribbons and boron nitride nanoribbons. Effect of electron doping on the NFE states in graphane nanoribbon superlattice has been studied, and it is possible to open a vacuum transport channel via electron doping.
