Abstract

The optical response of magnetically aligned singlewall carbon nanotube films was studied by polarizationdependent reflectance measurements in the infrared and visible frequency range as a function of external pressure. At ambient pressure the optical properties are anisotropic and show the characteristic excitations (broad infrared peak and optical transitions). The pressure-induced shift of the optical transitions reveals an anomaly at a critical pressure Pc≈2.7 GPa. This anomaly can be attributed to the circular-to-oval structural phase transition in the nanotubes.
