A single polymer nanowire photodetector

The solution-assisted template wetting is successfully exploited for high-yield controlled synthesis of poly(9,9-dioctylfluorenyl-2,7-diyl)-co- (bithiophene) (F8T2) nanowires with good control over wire structure and morphology. The photoconductivity measurements of F8T2 nanowire devices are also presented, which yield single-nanowire responsivities and external quantum efficiencies under monochromatic illumination, competitive with reported data for single-inorganic-nanowire devices. The nanowires are fabricated under ambient conditions via solution-assisted wetting of porous anodized alumina membranes. A scanning electron microscopy image demonstrate the efficiency of the solution-wetting process for high-yield preparation of the nanostructures. The nanostructures will demonstrate as nanoscale building blocks with potential for integration into future hybrid nanophotonic devices and systems.
