Abstract:
The Raman spectra of single-wall carbon nanotubes under the pressures up to 10 GPa have been measured in situ in diamond anvil cell. The “breathing” mode was clearly seen at pressures below 2 GPa and disappeared at higher pressures. The splitting of TO mode was kept at all steps of pressurizing. This mode shifted from the position 1592 cm−1 (at ambient pressure) toward high frequencies almost linearly with the pressure. The shift rate (4.9 cm−1/GPa) appeared to be very close to that of graphite. The irreversible broadening and overlapping of the split components of TO mode at pressures above 2.5 GPa have been observed. A polymerization of nanotubes inside ropes followed by the graphite needles formation is discussed as a possible mechanism of the tube structure transformation under the pressure.
