High-pressure Raman measurements on single-wall carbon nanotubes (SWNTs) have been carried out in a diamond anvil cell by using two wavelength lasers: 830 and 514.5 nm. Irrespective of using a pressure transmitting medium (PTM) or not, we found that nanotubes undergo similar transformations under pressure. The pressure-induced changes in Raman signals at around 2 and 5 GPa are attributed to the nanotube cross-section transitions from circle to ellipse and then to a flattened shape, respectively… CONTINUE READING
