Transport properties of a single layer armchair h-BNC heterostructure

Based on first-principles approach, the transport properties of single layer armchair h-BNC heterostructures are investigated. The results show that NDR behaviors, whose peak-to-valley ratio reaches ten, and rectifying performance with rectification ratio of up to 21, can be observed while the graphene nanoribbon and BN nanoribbon are contacted with the interface C-B, with a certain element proportion. The analysis on microscopic nature reveals that the electrostatic potential, electronic transmission strength and distributions of molecular states can be tuned by contact atoms and element proportions. © 2011 American Institute of Physics.
