Electron Microscopy

Electron microscopes

Currently, we have two transmission electron microscopes (TEMs) and one scanning electron microscope (SEMs): we have a range of equipment for sample preparation, including mechanical and chemical polishing equipment, dimplers, ion thinners and access to a focused ion beam thinner.

Surface Physics

ÄKTA Purifier - Protein purification system

This is a versatile fast protein liquid chromatography (FPLC) purification system. Proteins and peptides can be purified or separated using typical chromatography techniques:

  • Ion-exchange
  • Gel filtration
  • Hydrophobic interaction
  • Affinity

Scanning Tunneling Microscope

Our Agilent scanning tunneling microscope (STM) is used for fundamental nucleation and growth studies and single molecule electron transport measurements. It allows full control of the sample environment during in-situ and ex-situ imaging.

Atomic Force Microscope - Dimension V

This recently upgraded Dimension V microscope is equipped with a Nanoscope V controller and a TUNA2 module. The system has tapping, contact, torsional resonance, tunneling AFM (TUNA), conducting AFM, and TR-(TUNA)mode capabilities and includes a vibration isolation table and an acoustic hood to minimise background noise.

Electrochemical Cell

Computer control permits the electrodeposition of magnetic nanostructures with layer thicknesses down to a few times the diameter of a single atom. We also have a rotator for using rotating disk electrode techniques, which gives us control of the mass transport conditions in a solution.

Optics Lab

Our optics laboratory is used for in-situ studies of electrodeposited thin films. We measure stress by laser beam deflection, investigate magnetic properties using the Kerr effect, and study film growth by oblique incidence reflectivity difference measurements.

SQUID Magnetometer

The MPMS-XL from Quantum Design is equipped for DC and RSO (Reciprocating sample option) measurements and continuous low-temperature operation. The available field range is 0.01 to 5T, with a temperature range of 2K to 300K.

Static and dynamic light scattering (SLS and DLS)

The Brookhaven Instruments BI-200SM allows studies of both static and dynamic light scattering experiments. The goniometer provide controlled, multiangle measurements such as:

  • Particle sizing and size distribution
  • Mw, Rg, A2 (second virial coefficient) for polymer and protein solutions
  • CONTIN, Zimm plots, Guinier plots

Vibrating Sample Magnetometer

The Lakeshore vibrating sample magnetometer (VSM) is used to measure the magnetic moment of small samples in different applied fields. It works by detecting the voltage induced in a set of pick-up coils by the varying field associated with the vibrating sample.
