Facilities

Extensive laboratory equipment is available in the group - principally ultra-high vacuum (UHV) rigs, but also including electrochemistry and high vacuum equipment. Technical support is provided by Mr. Rob Johnston.

The group's research takes advantage of several central facilities, including the BESSY II synchrotron radiation source in Berlin, the European Synchrotron Radiation Facility (ESRF) in Grenoble and the ARPES beamline at the ASTRID Synchrotron Radiation Source in Aarhus, Demark.

Most of the UHV chambers in the group at Warwick have facilities to make LEED, XPS and AES measurements, and both the MBE and PLD chambers have RHEED systems (reflection high energy electron diffraction, using a different geometry but with very similar application to LEED). Some undergraduate projects offered in the group also use one of the LEED systems. We also have a 'low current' LEED system operating with a channel plate instead of usual phosphor screen and high voltage grid. The nanoamp beam currents attainable avoid problems with electron beam-induced dissociation of adsorbed molecules of interest.

Science City Initiative

The group recently benefitted from £1.5M of capital investment funding for new equipment from Advantage West Midlands (AWM), under the Science Cities initiative, and we have purchased two completely new UHV growth and surface analysis systems. The first is a combined pulsed laser deposition (PLD) facility with in-situ high pressure RHEED, XPS and variable temperature STM/AFM capability, and the second is an ultra-high resolution electron spectroscopy system combining state-of-the-art UV and monochromatic X-ray photoelectron spectroscopy.

Supporting Techniques

We also enjoy the high level of support possible in a major condensed matter physics research department for microscopy, X-ray diffraction and magnetic measurements. The magnetic materials epitaxy programme benefits from interaction with the Superconductivity and Magnetism Group and the X-ray Magnetic Scattering Group. We can access the in-house vibrating sample magentometer (VSM) and superconducting quantum interference device (SQUID) for measuring the basic magnetic properties of epitaxial layers and nano-clusters. Furthermore, we have recently started collaborations using more advanced techniques based at central facilities: X-ray scattering at the SPring-8 synchrotron in Japan with Dr. Jon Duffy and polarised neutron reflectometry at ILL in France. All our thin film growth benefits from interaction with the Microscopy Group, which boasts facilities for scanning electron microscopy, transmission electron microscopy and atomic force microscopy (including magnetic force capability). Finally, we have strong interactions through our highly mismatched alloys programme with several laboratories who perform Hall and infra-red measurements to elucidate basic electronic structure parameters.

Safety Information

Please read the following notes on local rules for safety and training in the SITF Group: sitfsafety.pdf

Please use the following risk assessment form when starting project work, and update your form when you begin using new equipment or procedures: sitfra.xls

We recommend that you keep it in electronic form and update. If you have to hand in a risk assessment by a certain date make sure you have discussed it with staff and students thoroughly before printing it and getting it signed off.
