Here we put the output file with calculated plasmon frequencies for SWNTs with diameter from 0.5 to 2 nm. The columns include the following data:
Efermi - Fermi energy in eV
Density of charge means:
n,m are chiral indices of SWNT
family is
diameter of SWNT is calculated as:
Ei, Ej are initial and final subbands respectively
Plasmon frequency w_p in eV corresponds to the peak position in absorption spectra (for more details see https://arxiv.org/abs/1811.11451)
branches column is used to mark down different types of plasmons, which we call branch1, branch2, etc.
ratio is defined as:
Absorption column contains intensity of the plasmon absorption peak
The data is plotted in Fig. 6 in the paper "Intersubband plasmon excitations in doped carbon nanotubes".
