Electron Microscopy and X-Rays

Electron Microscopy and X-Rays

The Advanced Electron Microscopy, Imaging & Spectroscopy (AEMIS) facility is a core multi-user facility that features cutting-edge instrumentation, techniques and expertise required for the characterisation of samples in the physical and life sciences.

This facility focuses on materials and biological research, the development of novel techniques and instrumentation, as well as providing training, technical support and consultation in the areas of electron microscopy and spectroscopy. The centre facility houses several electron microscopes that can probe the physical, electronic, biological, and chemical structure of matter down to the atomic scale.

These instruments are coupled with advanced in-situ holders, in which the environment is controlled to match near-realistic conditions of operation, and the sample’s behaviour is recorded dynamically in real time. State-of-the-art support facilities also are available, including standard specimen preparation equipment and an image analysis laboratory.

    Powder or Thin Film X-ray diffraction – an analytical technique used for phase identification and quantification of crystalline materials. It provides information on unit cell structure parameters and crystallographic orientation. Also used for contaminant detection and analysis. Grazing Incidence X-Ray Diffraction can also be done.

    Reciprocal Space Mapping – is used to identify crystallographic orientation, composition, stress, and mismatch of heterostructures.

    X-ray Reflectivity (XRR) – is used to identify film thickness, density, and interface roughness.
