Abstract

How electron energy damp to lattice vibrations (phonons) in MXenes has not yet been unraveled. Here, the authors demonstrate an energy damping channel in which the Ti3C2Tx plasmonic electron energy transfers to coherent phonons by nonthermal electron mediation after Landau damping, without involving electron-electron scattering.
