- The effect of metal-molecule contacts in molecular junctions is studied based on the analysis of a statistically significant number of devices and a proposed multibarrier tunneling (MBT) model, where a metal-molecule-metal junction is divided into three individual barriers: a molecular-chain body and metal-molecule contacts on either side of molecule. Using the MBT model with the statistical analysis, we could derive and distinguish decay coefficients for contact barriers (棺1, 棺2), contact-dependent and contact-independent decay coefficients (棺0 vs 棺body), and specific contact resistances in terms of different molecular length and different natures of metal-molecule contacts. © 2007 The American Physical Society.
