The interaction between C60 fullerene molecules and single-chirality (11,10) single-walled carbon nanotubes (SWCNTs) is demonstrated by probing the optical transitions in (11,10) peapods by optical microspectroscopy. The results of the (11,10) SWCNTs and (11,10) peapods are compared to multi-chirality SWCNTs and peapods. The absence of the fine structure of the absorption bands in the case of (11,10)...
In this work, phosphorous-doped single-walled carbon nanotubes have been synthesized by the thermal decomposition of trimethylphosphine using a high-vacuum chemical vapor deposition method. Furthermore, a modified density-gradient-ultracentrifugation process has been applied to carefully purify our doped material. The combined use of Raman and X-ray photoelectron spectroscopy allowed us to provide...
Single-walled carbon nanotubes (SWCNTs) are seamless cylindrical tubes consisting of carbon atoms with diameters ranging from less than one nanometer to a few nanometers. The arrangement of carbon atoms in a SWCNT is uniquely specified by using a pair of integers (n,m) referred to as the chiral indices. While the detailed structures, such as a carbon–carbon bond length, should be important, they have...
Site selective high resolution photoemission and X-ray absorption have revealed the complex interplay between ferrocene and single-walled carbon nanotubes (SWCNTs) upon filling. The use of ultraclean and metallicity sorted nanotubes as starting material and a subsequent ferrocene filling, yields metallicity sorted hybrids, where the details of the internal charge transfer from Fe to the SWCNTs have...
