Can tunneling current in molecular junctions be so strongly temperature dependent to challenge a hopping mechanism? Analytical formulas answer this question and provide important insight into large area junctions

Abstract
The single level model predicts that tunneling current can varies with temperature over several of magnitudes, challenging thereby the hopping mechanism, and is able to estimate the number of current carrying molecules in large area junctions.
