Pressure dependence of Raman modes in double wall carbon nanotubes filled with α-Fe

1 shows the calculated normalized collapse pressures, as function of the inner tube diameter, for the single-wall (green triangles), double-wall (blue circles), and triple- wall

ABSTRACT We demonstrate wide-band ultrafast optical pulse generation at 1, 1.5, and 2 μm using a single-polymer composite saturable absorber based on double-wall carbon

To have a better insight and to learn about dispersions of nano- tubes in a polymer matrix we incorporated DWNTs in PEEK be- cause as we will see, double wall carbon nanotubes

By comparing the main Raman bands and their temperature coefficients of pristine and filled carbon nanotubes, we find evidence of a decreased interac- tion between the carbon atoms

When excited at 514 nm as compared to at 633 nm, the spectral position of the G band of the inner tube remains the same, while changes in the position of the Fermi level with

We combine the influence of the G-band shape as a func- tion of chemical doping and hydrostatic pressure to separate contributions from inner and outer tubes and to assign an
