Semiconducting nanowires are promising building blocks for many existing and emerging applications in electronics and optoelectronics. Depending on the composition of materials, semiconducting nanowires can be classified into group IV (Si or Ge), group III-V (GaAs, InP, InAs etc.), group II-VI (oxide or chalcogenides) or other nanowires with a semiconducting bandgap. With several decades of effort, semiconducting nanowire research has streamlined into several frontiers, namely nanoelectronics, nanophotonics, nanoelectronic-bio interfaces, optoelectronics and energy harvesting/conversion and storage. While the synthesis of semiconducting nanowires with controllable size seems trivial nowadays, the exquisite control of interfaces, superlattices or modulated heterostructures that lead to diverse multifunctionality with augmented performance is still demanded. More profound understanding of the charge carriers and their interactions among themselves or with other elemental excitations in both high temporal and spatial resolution is still required, which have important implications to many diverse applications in solar energy harvesting, energy storage, light-emitting devices and nanolasers as well as interfacing to biological applications. Innovative ideas or device concepts are still in great need for next generation smart and integrated nanoelectronic and nanophotonic devices for biological scaffolds.

This symposium will focus on the state-of-the-art synthesis of semiconducting nanowires and their mechanistic understanding, structural/electrical/optical characterization, and their applications in various functional devices. Novel syntheses that offer exquisite control of size, anisotropy, interfaces, defects, doping, guided growth etc. will be encouraged. Experimental efforts in the fundamental understanding of the electronic and photonic microscopic processes that lead to enhanced performances in energy harvesting and conversion, electronic and optoelectronic devices are highly appreciated. We also look for computational and modeling investigations that provide new insight into the light-matter interactions in nanowires or nanowire arrays and heterostructures. Methods that direct the organization of nanowires into large area arrays or interconnected networks for flexible films or biological scaffolds will also be considered. Semiconducting nanowires have evolved into a highly disciplinary field with active researchers from various fields of physics, chemistry, materials science, engineering sciences and biology, therefore the inherent interdisciplinarity will be highly considered and leveraged with an aim cultivate innovative new directions during the conference.
