Is Molecular Rectification Caused by Asymmetric Electrode Couplings or by a Molecular Bias Drop?

Abstract

We investigate possible causes of molecular rectification in electrode−molecule− electrode junctions. By using a simple model and simulated conductance histograms, we show that a molecular bias drop is responsible for rectification; conversely, asymmetric molecule−electrode couplings do not directly result in rectification. Instead, the degree of coupling… (More)
