摘要：

The pressure dependence of the high-energy Raman modes in single- and multi-walled carbon nanotubes was measured in the range 0-10 GPa. We found the pressure coefficient to be linear in both materials but 25% smaller in MWNT. Given that the curvature effects on vibrational properties of the rolled-up graphene sheets are small, we can explain this difference simply with elasticity theory.
