Abstract

High pressure Raman experiments were performed on the model system of double-wall carbon nanotubes. Changes in the resonance Raman profile of the radial breathing modes provide a unique demonstration of the inner tubes' band gap reduction with pressure. The overall trend of the internal tubes' normalized mode pressure coefficients vs frequency reveals the size-dependent properties of individual carbon nanotubes. Moreover, their quasilinear grouping, attributed to the inner-outer tube (intratube) coupling and its tube spacing dependence, manifests the existence of specific inner-outer tube combinations.
