Ultrafast investigation of electron dynamics in multi-layer metals

Ultrafast time-resolved pump–probe studies of energy relaxation and transport in polycrystalline single and multi-layer metal films are presented. The dependence of the surface electron temperature on the film structure was investigated. Vanadium was studied as possible padding layer for increasing...

Zusammenfassung:	Ultrafast time-resolved pump–probe studies of energy relaxation and transport in polycrystalline single and multi-layer metal films are presented. The dependence of the surface electron temperature on the film structure was investigated. Vanadium was studied as possible padding layer for increasing the laser damage threshold of metal mirrors. The results, for 300 K < T e
