Effect of a liquid pressure-transmitting medium on the high pressure behavior of open- and closed-end single-walled carbon nanotubes and of C60-peapods

In situ synchrotron X‐ray diffraction measurements of three types of single‐walled carbon nanotubes (SWNTs) (open‐ and closed‐end, and C60‐peapod samples) under high pressure using a cubic anvil press with a liquid‐pressure‐transmitting‐medium (LPTM) were carried out. Comparing with a previous experiment using a solid‐pressure‐transmitting‐medium, it was found that the high pressure behavior of SWNT bundles is much affected by the LPTM. In order to investigate the dependence of the LPTM effect on the tube‐end structure, in situ Raman scattering measurements were also performed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
