Charge transport in molecular junctions and microfluidic devices

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 doesnt have time to form, and its effects can be ignored.
