Experimental Techniques
-
Angle Resolved PhotoEmission Spectroscopy (ARPES):
The FOM-Amsterdam Momentum-Space
Microscope - FAMoS - made possible by an infastructural grant from the foundation FOM (and also supported by funding from the UvA) offers excellent ARPES performance (2meV, 0.1° resolution,
computerized rotation about three angular axes [polar, azimuth and tilt] at a
sample temperature of down to 14K).
- Ultra High Vacuum Low Temperature Scanning Tunneling Microscope (UHV LT-STM):
Commercially available STM/STS system with outstanding performance (drift of only a few Angstrom in 12 hours for 4.5-15K, pm resolution and < 0.5 mV resolution).
- Travelling solvent floating zone crystal growth (Dr. Yingkai Huang)
-
Resonant dynamical x-ray light scattering
Synchrotron-based coherent scattering can be used to probe the dynamics nanoscale order in the spin, charge or orbital order of correlated systems. With the advent of x-ray lasers this technique will come of age in the next few years.
- photoemission of core and valence levels
