Electron transfer in hybrid molecular solid-state devices

Electron transfer (ET) in organic-inorganic hybrid structures is of interest for applications in optoelectronics. The study of these hybrid structures is difficult because contact formation is often destructive. We have experimented with the lift-off/float-on technique to create metal contacts in a gentle manner. We present results of these experiments and initial data on silicon/octadecyl trichlorosilane (OTS)/silver junctions where the metal contact was prepared by evaporation. The presence of the OTS greatly affects the current-voltage characteristics of such a junction.
