Effects of pressure transmitting media on Raman features of single-walled carbon nanotubes
Abstract
We have performed high pressure Raman studies of single-walled carbon nanotubes (SWCNTs) by using different organic solvents as the pressure transmitting medium (PTM). A linear dependence of pressure coefficient of Raman G band is found with the molecular weight of organic solvent. In addition, according to the experimental data and a comparative analysis of pressure measurement without the PTM, we explain the occurrence of plateau and hardening behavior of Raman G and D ∗ bands upon increasing pressure.
