Influence of Illumination on the Electrical Transport Properties of Single Molecules and Small Layers of Molecules — •Jan U. Würfel¹, Heiko B. Weber¹, Joachim Reichert¹, Marcel Mayor¹, and Hilbert v.

We study the influence of light on the conductance properties of conjugated molecules. To obtain molecular junctions, we apply two different methods: First, single molecules are contacted via the mechanically controlled break-junction technique [1]. Second, molecular monolayers are self assembled in a 50 nm diameter nanopore sandwiched between two gold surfaces. Experimental progress is discussed.
