Abstract: In this work, we investigate methods to determine the average length for cotunneling in self-assembled gold nanoparticle arrays spaced with alkanethiols. 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.
