Abstract: We study the impact of optical field-enhancement effects on theoptoelectronic properties of metal nanoparticle arrays. Applying a focused ionbeam lithography in combination with an electron beam deposition technique wecan pattern electrical contacts in a way to give rise to an electromagneticfield-enhancement. A further field-enhancement is achieved by the plasmonresonance of the particles. Both effects are directly observed in thephotoconductance of the arrays.
