Title: Optical Spectroscopy of Individual Carbon Nanotubes
Abstract: Electronic and optical properties of single-walled carbon nanotubes depend sensitively on the nanotube chirality. Single tube spectroscopy provides a powerful too to probe the chirality-dependent physics in nanotubes. In the talk, I will describe a high-throughput optical imaging and spectroscopy technique that enables in-situ characterization of single tubes on substrate and in functional devices. I will show that systematic spectroscopy of individual double-wall nanotubes indicate strong electronic coupling between the inner- and outer-wall tubes that vary strongly with the nanotube chirality. I will also discuss our recent progress to probe 1D plasmon of Luttinger liquid in metallic carbon nanotubes.
