We report the observation and systematic investigation of the space
charge effect and mirror charge effect in photoemission spectroscopy.
When pulsed light is incident on a sample, the photo-emitted electrons
experience energy redistribution after escaping from the surface
because of the Coulomb interaction between them (space charge effect)
and between photo-emitted electrons and the distribution of mirror
charges in the sample (mirror charge effect). These combined Coulomb
interaction effects give rise to an energy shift and a broadening
which can be on the order of 10 meV for a typical third-generation
synchrotron light source. This value is comparable to many fundamental
physical parameters actively studied by photoemission spectroscopy
and should be taken seriously in interpreting photoemission data
and in designing next generation experiments.
