| Abstract: | In this work, electron energy spectroscopic mapping of surface plasmon of Ag nanostructures on highly oriented pyrolytic graphite is reported. Benefitting from the angular dispersive feature of the present scanning probe electron energy spectrometer, a multi-channel detection mode is developed. By scanning along one direction, the two-dimensional intensity distribution of Ag surface plasmon excitation due to the collision of electron emitted from the tip can be obtained in parallel. The spectroscopic spatial resolution is determined to be around 80 nm. |
