Raman response of FeCl3 intercalated single-wall carbon nanotubes at high doping

A detailed study on the photoselective Raman response of p-type intercalated single-wall carbon nanotube (SWCNT) is presented. Here, we focus on the high doping region. The shift of the G-line is used to monitor the doping level of the p-type intercalated SWCNT using irontrichloride. Special emphasis is given on the changes in the dispersion of the D- and G'-lines as a function of doping. For very high doping levels a decrease of the slope is observed.
