Non-Equilibrium Pathways for Excitation of Bulk and Surface Phonons through Anharmonic Coupling
C. Brand, V. Tinnemann, A. Hanisch-Blicharski +5
Upon impulsive optical excitation of solid-state materials, the non-equilibrium flow of energy from the excited electronic system to the lattice degrees of freedom typically happen…
