Electron-electron interaction in carbon nanostructures
摘要
The electron-electron interaction in carbon nanostructures was studied. A new method which allows to determine the electron-electron interaction constant from the analysis of quantum correction to the magnetic susceptibility and the magnetoresistance was developed. Three types of carbon materials: arc-produced multiwalled carbon nanotubes (arc-MWNTs), CVD-produced catalytic multiwalled carbon nanotubes (c-MWNTs) and pyrolytic carbon were used for investigation. We found that =0.2 for arc-MWNTs (before and after bromination treatment); = 0.1 for pyrolytic graphite; 0 for c-MWNTs. We conclude that the curvature of graphene layers in carbon nanostructures leads to the increase of the electron-electron interaction constant .
