摘要:Using first-principles density functional theory and non-equilibrium Green's function formalism for quantum transport calculation, we have investigated the electronic transport properties of the unsymmetrical C-121-based molecular junction. Our results show that the current-voltage curve displays a negative differential resistance phenomenon in a certain bias voltage range. The mechanism for the negative differential resistance phenomenon is suggested. The present findings could be helpful for the application of the C-121 molecule in the field of single molecular devices or nanometer electronics. (C) 2011 Elsevier B.V. All rights reserved.
