(179d) Synthesis and Characterization of Charge Transfer Complex Micro/Nanowire Junctions and Their Application in Gas Sensing

Micro/nanowire junctions are of important technological interest due to their unique interfacial and electric properties. Junctions are the transport bottlenecks in network-based micro/nanowires, understanding the properties of these junctions and their connectivity is crucial to understanding and controlling electrical conduction through these networks. In this talk, we show the results of the electrochemical growth of conductive micro/nanowires of charge transfer complexes (CTC). CTC wires are grown on adjacent microelectrodes by applying periodically interchanged potentials until connections between the electrocrystallized wires are formed. The morphology and electric properties of the junctions are characterized. The findings are used to fabricate new devices for gas sensing.
