Popis:	We demonstrate a procedure for fabricating back-gate-type sub 5 nm gap junctions without using electron beam lithography. The fabricating procedure contains two photolithographic processes followed by shadow evaporation and oxygen plasma ashing. Oligo(para-phenylenevinylene) trimers (OPV3) attached to methylthiol at both ends were bridged between these junctions. The temperature dependence of OPV3 conductance indicated the characteristic behavior of hopping conduction. The results indicate that these junctions can be used in the study of conductance measurements through molecular wires.
