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 and several other crystal growth techniques (Dr. Ying Kai 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.
  • High energy photoemission spectroscopy of core and valence levels:
    This technique is utilized to study buried interfaces in oxide heterointerfaces. The much larger electron escape depth at these energies allows one to probe interfaces buried several nanometers below the surface.
  • Low energy electron diffraction characterization of crystal surfaces
  • Resistance and Hall effect using ac- and dc-techniques; Heat capacity with semi-adiabatic technique; Dilatometry (thermal expansion and magnetostriction) using a capacitance dilatometer ; Ac and dc-susceptibility Pressure cells of the clamp type for pressures up to 20 kbar
