The Interface Analysis Centre provides a wide range
of techniques for the analysis of interfaces in solid-state materials.
Our range of techniques can be separated into two areas of speciality:
Near Surface Techniques and Surface Techniques.
Surface Techniques
Auger Electron Spectroscopy (AES)
All elements, except H and He, can be detected in the top
few atom layers. Semi-quantitative. Good spatial resolution.
Instruments equipped with fracture stages (both impact and
tensile), and depth profiling facilities.
Secondary
Ion Mass Spectrometry (SIMS)
Static SIMS: All elements detected, most to ppm detection
levels. High mass numbers detected, good for analysis of polymers,
with a spatial resolution of ~3 µm. Depth profiling
is also possible.
X-ray
Photoelectron Spectroscopy (XPS)
Nearly all elements detected. Semi-quantitative with chemical
state information. The ESCASCOPE has spatial resolution
of 10 µm when mapping and 50 µm in analysis.
Focused
Ion Beam (FIB)
Milling and imaging tool for device editing, defect and
failure analysis, TEM sample preparation, sample sectioning
and microscopy is also possible
Near
Surface Techniques
Scanning
Electron Microscopy (SEM) with EDX analysis
All elements except H and He can be detected in the top few
atom layers. Semi-quantitative. Good spatial resolution. Instruments
equipped with fracture stages (both impact and tensile), and
depth profiling facilities.
We also have an Environental SEM, for low vacuum analysis
of wet, or larger environmental samples.
Laser
Raman Spectroscopy (LRS)
Used to identify materials by characterising the distinctive
energies of the chemical bonds or to distinguish between
different phases of the same material. We offer MicroRaman
analysis and mapping of materials, as well as spot Raman
analysis of large and in-situ components, e.g. alumina-
and zirconia-based oxides on turbine surfaces.
These techniques are available to commercial, industrial,
and academic institutions at highly competitive rates. Please
contact us to discuss
your requirements.
