Tuning Negative Differential Resistance in a Molecular Film
arXiv:cond-mat/0503765 · doi:10.1063/1.1931822
Abstract
We have observed tunable negative differential resistance (NDR) in scanning tunneling spectroscopy measurements of a double layer of C60 molecules on a metallic surface. Using a simple model we show that the observed NDR behavior is explained by voltage-dependent changes in the tunneling barrier height.
