ORDERED STRUCTURE AND ELECTRICAL TRANSPORT IN REGIOREGULAR POLY (3-HEXYLTHIOPHENE) NANOWIRES FABRICATED BY TEMPLATE WETTING METHOD
Individual semiconducting nanowire offers the promise of achieving high-density nanochips as building blocks to demonstrate digital logic operations and basic computation. The electrical transport through single nanowire is particularly important since it can be used as a conducting channel, a key component for logic. Therefore predictable and controllable conductance of every single nanowire is critical to nanoscale electronics properties, and the study on the conductivity of nanowires is of vital importance. The regioregular poly(3-hexylthiophene) (P3HT) has proved to be one of the most promising semiconducting polymers due to its excellent solvent-processibility and charge transport capability. In this paper, we produced P3HT nanowires by wetting with polymer melts porous anodized alumina membranes whose diameter, length can be easily controlled. The electrical properties of individual P3HT nanowires were investigated, which can be controlled in a predictable manner over the range from insulator to metal by doping. The electrical measurements were performed in the conductive scanning probe microscope, which is a powerful tool for the electrical characterization.1-3
