Raman Scattering Cross Section of Confined Carbyne

Abstract

We experimentally quantify the Raman scattering from individual carbyne chains confined in double-walled carbon nanotubes. We find that the resonant differential Raman cross section of confined carbyne is on the order of $10^{-22}$ cm${}^2$sr${}^{-1}$ per atom, making it the strongest Raman scatterer ever reported.
