Recently we demonstrated a new mechanism of plasmon-induced electronic transport in hybrid metal nanoparticle-molecular devices. The mecahnism realizes enhancements of up to a factor of 200. The hybrid structures consist of arrays of gold nanoparticles linked by (porphinato)zinc(II) oligomers. Here we examine the role of metal particle size, spacing, and molecular length on the transport mechanisms. Understanding the charge transport through the structures allows the relative roles of nano antennae field focusing and hot electron distribution to the current enhancement to be compared. This phenomenon offers a pathway to wide ranging control of the opto electriconic transport properties which enables concepts of energy harvesting, energy transduction and optoelectronic circuits.
