Collective oscillations in a single-wall carbon nanotube excited by fast electrons

摘要: Electron energy loss spectroscopy is a well adapted tool for the investigation of valence excitations individual nanometer-size particles. The interpretation spectra such small particles, however, relies in most cases on quantitative comparison with simulated excitation probabilities. Here we present formalism developed data single-wall carbon nanotubes based hydrodynamic theory plasmon by high-energy electrons. are modeled as twodimensional electron gas confined circumference cylinder. probabilities, directly comparable to measurements, discussed various parameters.
