TL;DR
This paper reports the first experimental measurement of the Raman scattering cross section of confined carbyne chains, revealing it as the strongest Raman scatterer ever observed, with potential implications for nanomaterials.
Contribution
It provides the first quantitative measurement of the Raman cross section of confined carbyne, demonstrating its exceptional scattering strength.
Findings
Raman cross section of confined carbyne is approximately 10^{-22} cm^2 sr^{-1} per atom.
Confined carbyne exhibits the strongest Raman scattering among known materials.
Experimental quantification confirms the potential of carbyne in Raman-based applications.
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 cmsr per atom, making it the strongest Raman scatterer ever reported.
