  • Electro-transmittance of molecular junctions was characterized electrically and studied optically at 410nm and 532nm. Between 1kHz and 100kHz there was no qualitative difference between the control samples and the molecular junction samples, however there were difficulties with reproducibility of the quantitative behaviour, so no hard conclusions could be drawn. A microfluidic capacitor device was designed and fabricated to study the electrical double layer, using standard microfabrication techniques. A complimentary flux corrected transport simulation was written using the same experimental geometry and the results of this study found qualitative agreement between the simulation and experiment. The experiment produced results about the concentration dependence of the double layer formation time which allows an estimate of the required frequency of an AC electrical signal for which the electrical double layer doesn’t have time to form, and its effects can be ignored.
