The electronic structure of transition metals and their oxides with emphasis on the interaction between electrons. The experimental methods are:
- Laser-based photoelectron spectroscopy and microscopy:
By using femtosecond lasers as excitation light sources, the ultrafast dynamics of the electronic structure of surfaces, ultrathin films, and nanostructures are studied.
- High-order harmonic generation at megahertz repetition rates:
High-order harmonics of MHz femtosecond lasers provide a widely tunable photon energy range in pump-probe photoemission experiments without the limitation from the space charge effects.
- Double photoemission spectroscopy:
With double photoemission, where an incident photon excites a pair of correlated electrons from solids, the interaction between electrons can be directly studied by the characteristic two-dimensional energy and angular distributions of electron pairs.
