One dimensional semiconductor nanostructures are an emerging class of materials that represent attractive building blocks for nanoscale electronic and photonic devices. However, while inorganic materials have been explored in depth, the challenge of fabricating organic nanowire- and nanotube-based devices has yet to be as comprehensively addressed. To this end, my group has recently developed methods both for high yield synthesis of semiconductor nanowires and nanotubes based on conjugated polymer and small molecule organic materials and for assembly of these novel wires into integrated nanodevices.1 We have successfully demonstrated key nanophotonic properties at the single nanowire level that include polarized light emission, polarizing energy transfer, wave-guiding, optical microcavity effects, and optically pumped lasing. Further studies are presently underway in areas such as nanowire- and nanotube-enabled explosives detection, electrical conduction and photo-detection. These devices may find many opportunities in future applications such as nano-optical routing, wave-guiding, emission and detection, data storage, sensing and near-field optics. In this talk, details of results achieved within these themes will be presented.
