Abstract

High pressure Raman experiments on boron nitride multi-walled nanotubes show that the intensity of the vibrational mode at~1367 $cm^-^1$ vanishes at~12 GPa and it does not recover under decompression. In comparison, the high pressure Raman experiments on hexagonal boron nitride show a clear signature of a phase transition from hexagonal to wurtzite at~13 GPa which is reversible on decompression. These results are contrasted with the pressure behavior of carbon nanotubes and graphite.
