By deposition of molecules from solution between two gold leads we were able to determine the conductance of the OPE3 at (1.6±0.3)·10−4G0. The measurement speed of the LabVIEW control program for this experiment was improved by more than a factor of 7 compared to the previous version.Show less

Cotunneling currents can be as low as 10 fA, requiring the development of robust measurement techniques to lower the noise floor. We present a comparison of different methods for finding the effective cotunneling length N. Preliminary findings on a variety of arrays indicate the onset of the cotunneling regime, but that there is no distinction in N between choice of alkanethiol in the array.Show less
