Techniques such as conductive atomic force microscopy and electrostatic force microscopy are applied to the study of photoexcited arrays of gold nanoparticles decorating an indium tin oxide coated glass substrate. The nanoparticles are partially covered by a thin semiconducting polymer. The change in the current and potential profiles of the composite metal-semiconductor sample after excitation at the plasmonic resonance frequency of the metallic nanoparticles is analyzed.
