N2 - Nanoscale-synthesized materials hold great promise for the realization of future generation devices. In order to fulfill the exceptional promise, new techniques must be developed that will enable the precise layout and assembly of the heterogeneous components into functional 'superblocks'. As one promising route to this end, rapid and spatially confined heating capability of laser irradiation has enabled precisely controlled nucleation and subsequent direct growth of nanowires at an arbitrary local region based on vapor-liquid-solid (VLS) mechanism. Spatial confinement of the nanowire growth region via focused laser beam illumination provides a convenient way to examine multiple growth parameters (temperature, time, illumination direction, and composition), thereby elucidating fundamental nanowires growth mechanisms. Furthermore, the work demonstrates an advanced method for direct synthesis of nanostructures for the purpose of practical rapid patterning including on demand multi-bandgap materials based nanowires.
