Attention: the beamlines ID01, ID03 and ID32 now belong to the ESRF Structure of Materials Group, and the pages for these beamlines will be moved to the new section starting 17 June 2009.

Beamlines and Laboratories: ID1 Anomalous Scattering ID3 Surface Diffraction ID32 Surface XRD, SEXAFS and X-ray Standing Waves Surface Characterisation laboratory Electrochemistry Laboratory

Synopsis

The surface and interface beamlines offer a variety of technique and sample environments for the study and analysis of surfaces, near surface structures and buried interfaces on the atomic to the micrometre length scale. The facilities are ideally suited to the study of samples relevant to the future developments in nano-technology.

Techniques include surface diffraction, grazing incidence small-angle X-ray scattering (GIDSAX) and combined X-ray standing wave (XSW) and X-ray photon spectroscopy (XPS).

ID1 is particularly well suited for the grazing-incidence techniques, both at high and low scattering angles, which can be performed simultaneously – without the necessity of remounting the sample – and in combination with anomalous scattering. A great deal of the scientific activity of the beamline is devoted to structural and morphological studies of quantum dots. At the Surface Diffraction Beamline ID3, there are two z-axis diffractometers for surface diffraction experiments. One is coupled to a multipurpose UHV system that allows us to carry out in situ MBE growth and the other is specially adapted for horizontal surfaces. Surface resonant magnetic diffraction and the study of gas/solid interfaces at atmospheric pressures are two projects of current interest. At ID32, surface diffraction, X-ray standing waves (XSW) and X-ray photoelectron spectroscopy (XPS) can be combined. An electron energy analyser can be used for up to 4800 eV kinetic energies of the electrons. Topics of current interest include solid/liquid interfaces in electrochemistry and high Tc superconductors.

Associated Facilities

The surface characterisation laboratory at ID32 has several UHV facilities including a scanning-tunneling microscope and transfer chambers. Note also that Beamline ID10B is available for surface and interface studies using grazing-incidence techniques.
