Conductance of Armchair GNRs with side-attached organic molecules

In this work we show a theoretical study of the transport properties of armchair graphene nanoribbon at which linear poly-aromatic hydrocarbon molecules (LPHC) are side-attached on the ribbon edge. We describe the system by a tight-binding model and calculate the local density of states and the conductance within the Green's function formalism. We found that the conductance curves reflect the energy spectra of the attached molecules, suggesting that AGNRs could be used as a spectrograph device. r 2008 Elsevier Ltd. All rights reserved.
