This thesis reports experiments and numerical calculations aiming at the observation and quantitative dissection of the microscopic mechanisms contributing to the temporal delays observed in time-resolved measurements of the attosecond photoelectric effect, i.e. the delayed appearance of the photoelectron in vacuum after excitation of metallic samples in with extreme-ultraviolet (XUV) radiation. We probe photoelectrons emerging from the metal surface and their respective frequency-resolved time delays with temporal resolution and accuracy on the 10 attoseconds time scale.     «
