Abstract

A new in-wire conversion method for the fabrication of organic semiconductor nanojunctions sandwiched between gold segments were developed, where the basic concept involves the electrochemical deposition of multisegmented nanowires followed by selective conversion of a metal segment. The experiment involve the exposure of segmented rod to TCNQ vapor for 2h, where the Ag segment was converted into needled of AgTCNQ some of which bridged the two Au segments. The developed method can be employed as an integrated method for the synthesis of AgTCNQ and the fabrication of nanoscale devices in a single step. The results exhibit the production of a gap-junction arrangement that does not require further processing of the organic layer after vapor-phase deposition of the molecular material.
