Abstract

We discuss some of the complex issues associated with the metrology of molecular electronic devices and describe an electrical characterization method to assess molecular crossbar devices. Experimental data is shown for an eicosanoic acid crossbar device that exhibits controllable switching hysteresis. This two-state system is due to the presence of molecules in the sample, but it is unlikely that it is due to an intrinsic property of the eicosanoic acid. It is most likely that a mechanism associated with the molecule-electrode interface is the cause of this hysteresis. These data exemplify the need for improved control and understanding of the detailed chemistry of molecule-electrode interfaces and illustrate that the properties of molecular electronic devices are determined by the entire device structure consisting of the molecules and the electrodes.
