Structure and property changes of single-walled carbon nanotubes under pressure
この論文をさがす
説明
Single-walled carbon nanotubes form raft-like bundles when they are produced by laser evaporation of graphite targets. When hydrostatic pressure is applied to the pristine carbon nanotubes, we found that the nanotubes can be compressed easily with a high volume compressibility of 0.024 GPa -1 . Though polygonization must have occurred under the present circumstances, there was no significant change such as a phase transformation from semiconducting to metallic was observed with electrical resistivity measurements within the pressure range (up to 2 GPa) we employed.
