题目：Optical Spectroscopy on Nanostructures

报告人：Prof. Yuen-Ron Shen (Department of Physics, University of California, Berkeley)

摘要：
Recent work on optical characterization of carbon nanotubes in our laboratory will be discussed. On Raman scattering, we have observed multiphonon Raman spectra up to 6 phonons from individual single-wall nanotubes. On excitonic transitions, we have obtained absorption spectra that show the existence of excitons in metallic single-wall nanotubes with a binding energy of about 50 meV.
