| Electron dynamics in solids comprise a rich spectrum of elementary processes, which occur on a femto- to attosecond timescale. Fundamental questions relate to the buildup of screening and electron correlations, ultrafast charge transfer and the coupling of electronic excitations to nuclear motions. In this talk I will review some of the current experiments on electron dynamics at surfaces, which have performed so far mainly on the femtosecond time-scale, and discuss perspectives for future attosecond experiments on solid surfaces. |
