  • 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.
