Abstract: | Charge transfer at surfaces, which is very important for surface photochemistry and other processes, can be extremely fast. This tutorial review shows how high resolution correlated excitation/decay spectroscopies of core excitations can be used to obtain charge transfer times at surfaces around or below 1 fs. Some results are described in more detail, and their meaning and theoretical modelling are discussed. A brief comparison to laser methods shows that there are differences in the processes they look at. |
