Mapping defects in a carbon nanotube by momentum transfer dependent electron energy loss spectromicroscopy

Momentum resolved electron energy loss (EELS) spectra of multi-walled carbon nanotubes (MWCNT) have been measured at the C 1s edge in a transmission electron microscope (TEM). We demonstrate that structurally sensitive electron linear dichroic (ELD) signals analogous to X-ray linear dichroic (XLD) signals (Najafi et al., 2008) [17] can be measured by TEM-EELS from individual MWCNT if sample tilt and deflection of the inelastic scattering signal …
