| Techniques usage | |||||||||
| Absorption / NEXAFS | Absorption spectra are measured in Auger yield. By changing sample orientation, the angle between the electric field E of the polarized light and and the normal to the sample surface can be varied in the range from 20 to 90 degrees. | ||||||||
| Photoelectron emission / Angular Resolved PES | The technique is available if the modified CTPO manipulator is used, which allows software controlled angular movements of the samples. | ||||||||
| Photoelectron emission / Photoelectron diffraction | Core level intensity is measured as a function of polar and azimuthal emission angles. The technique is available if the modified CTPO manipulator is used, which allows software controlled angular movements of the samples. | ||||||||
| Photoelectron emission / Time-resolved studies | Fast XPS allows monitoring the evolution of core level spectra (typical acquisition time between 4 and 10 seconds per spectrum), e.g. while exposing the sample to gases or during an annealing. | ||||||||
