Reflection high-energy electron diffraction from carbon nanotubes

Using reflection high-energy electron diffraction, we have observed diffraction patterns from both vertically aligned and randomly oriented multiwalled carbon nanotube samples. The patterns, for both samples, consist of rings and are similar to the patterns observed in x-ray diffraction from multiwalled carbon nanotubes. The ring radii are roughly consistent with powder diffraction from graphit...

Optical determination of electron-phonon coupling in carbon nanotubes.

We report on an optical method to directly measure electron-phonon coupling in carbon nanotubes by correlating the first and second harmonic of the resonant Raman excitation profile. The method is applicable to 1D and 0D systems and is not limited to materials that exhibit photoluminescence. Experimental results for electron-phonon coupling with the radial breathing mode in 5 different nanotube...

Conformations and coherences in structure determination by ultrafast electron diffraction.

In this article we consider consequences of spatial coherences and conformations in diffraction of (macro)molecules with different potential energy landscapes. The emphasis is on using this understanding to extract structural and temporal information from diffraction experiments. The theoretical analysis of structural interconversions spans an increased range of complexity, from small hydrocarb...

Shell buckling of individual multiwalled carbon nanotubes using nanoindentation

Although the mechanical behavior of carbon nanotubes has been studied extensively in recent years, very few experimental results exist on the shell buckling of nanotubes, despite its fundamental importance in nanotube mechanics and applications. Here we report an experimental technique in which individual multiwalled carbon nanotubes were axially compressed using a nanoindenter and the critical...
