Non-trivial phonon dynamics and significant electron-phonon coupling of the high frequency modes in a Dirac semimetal
Debasmita Swain, Akash Dey, Anushree Roy +2
Using finite temperature Raman spectroscopy, we investigate the electron-phonon interactions (EPI) and phonon-phonon scattering dynamics in the Dirac semimetal Cd3As2 in different…
