Detecting Phonon Overtones in Correlated Materials

To better understand electronic behavior in carbon-based materials such as graphene, fullerene, and carbon nanotubes, researchers used the ALS to detect faint overtones in lattice vibrations (phonons)—ripples in intensity that offer clues as to how strongly electrons and phonons are coupled. https://als.lbl.gov/detecting-phonon-overtones-in-correlated-materials/
