摘要: A pellet of as-grown multi-walled carbon nanotubes (MWNTs) prepared by compression was heat-treated at 3000°C for 30 min to eliminate metal impurities and a piece the 3000°C-treated boron doped with diffusion method. Electron energy loss (EEL) spectrum measurements an individual boron-doped MWNT (B-MWNT) selected from were taken along central line high resolution transmission electron microscope image, i.e. axis B-MWNT. Along line, K-shell excitation EEL composed two spectra, weak strong spectrum, obtained some positions, while other positions only recorded. Semi quantitative analysis near edge structure K-edge revealed that doping had place quite locally in
