Soft-X-ray ARPES gives access to fundamental electronic-structure parameters (Fermi surface, electron dispersions and effective masses, electron-boson interactions) with resolution in k-space. The use of soft X-rays allows exploring a wide range of quantum materials from bulk crystals to buried heterostructures and impurities |
Soft-X-ray RIXS gives access to strong electron correlations and electron-boson interactions, by probing the energy and momentum dependence of magnetic, orbital, charge and lattice excitations, for a wide range of quantum materials from bulk crystals to buried heterostructures and two-dimensional materials |
Instrument for multimodal 4D chemical imaging ('chemistry inspace and time'). Special focus on chemical tomography and time-resolved (operando) chemical imaging. Spatial resolution and sensitivity allows the investigation of a wide range of quantum materials from bulk crystals, two-dimensional systems to buried heterostructures and impurities |
