|Direct observation of the growth and evolution of nanowire heterostructures|
|Keywords: plasmonics, nanowires, transmission electron microscopy|
|Metal-dielectric heterostructures have received much interest in recent years because of properties due to the localized surface plasmon resonances at the metal/dielectric interfaces, such as sub-diffraction limit waveguiding and colossally-enhanced photoemission. Noble metal nanoparticle chains have been fabricated using several top-down methods such as lithography and templating, but the bottom-up approach of a peapodded nanowire is attractive because the nanoparticles form spontaneously within a protective ceramic nanowire shell during synthesis, and have the potential to be very well-defined in terms of size, spacing, shape, and interfacial orientation. Here we will present two complimentary transmission electron microscopy studies of these materials, to study their growth and evolution in situ, and to map their plasmonic characteristics on the nanometer length scale – providing a direct link between structure, synthetic conditions, and functionality.|
