Abstract

The study of metallic systems with time-resolved pump-probe spectroscopy allows one to investigate the thermalization dynamics of hot electrons. Two main lime scales are generally distinguished that correspond to a fast relaxation of the initial nonequilibrium electronic populations (typically 50-500 fs) followed by a thermalization of the hot Fermi distribution to the lattice (–0.5 to a few picoseconds).
