Description

We study the impact of optical field-enhancement effects on the optoelectronic properties of metal nanoparticle arrays. Applying a focused ion beam lithography in combination with an electron beam induced deposition technique we pattern electrical contacts in a way that they give rise to an electromagnetic field-enhancement. The field-enhancement is directly observed in an enhanced photoconductance of the arrays. Finite-difference time-domain simulations verify that an antenna effect is responsible for the observed increase in the photoconductance.
