Contour plots of the current described by eqn (4.1) as a function of nearest neighbor hopping distance and number of electrode contacts. The reorganization energy, λ, the length of the bridge, L, and the exponential decay constant, β, were chosen for relevance to a bacterial pilus. For all cases, kBT was taken as 1/40 eV. The figure informs at a glance the distance and contact constraints imposed upon each 2D cylindrical system for a given magnitude of current.
