FAIR practice

Antony N. Davies

Following our articles on the FAIR initiative, we now look at some examples of the FAIRification of data handling, collection and archiving.

Qualifying calibration samples for advanced thin film materials characterisation

Cornelia Streeck, Thomas Wirth, Wolfgang Unger, Burkhard Beckhoff

In this article the question of the certification of calibration samples for the characterisation of advanced thin film materials is addressed within the framework of reliable process control or quality management purposes. Reference measurement techniques can be used in order to address the gap in appropriate certified reference materials (CRMs) for thin film analyses. They allow for qualifying out-of-production samples originating from an operating production line as calibration samples. As a template for this procedure, CIGS [Cu(In,Ga)Se2] layers, that are absorber layers for high efficiency thin-film solar cells, have been used for establishing and validating reference-free X-ray fluorescence (XRF) analysis and Auger-electron spectroscopy (AES) as reference measurement techniques.

Fast and versatile ambient surface analysis by plasma-assisted desorption/ionisation mass spectrometry

Frank J.M. Rutten, Jasim M.S. Jamur, Paul Roach

This article tells us about another: “Fast and versatile ambient surface analysis by plasma-assisted desorption/ionisation mass spectrometry”. They show that surface analysis can greatly benefit from approaches using surface–plasma interactions and that PADI shows significant promise to become a valuable and versatile tool for this.

Infrared mapping spectroscopic ellipsometry

Karsten Hinrichs, Andreas Furchner

The authors describe “Infrared mapping spectroscopic ellipsometry”. Recent developments in fundamental and materials research have increased the value of mapping techniques such as ellipsometry. IR ellipsometry, since it operates in the mid-IR fingerprint region, provides complementary information on composition, structural properties and interactions

G-SIMS: a powerful method for simplifying and interpretation of complex secondary ion mass spectra

Ian S. Gilmore, Satoka Aoyagi, Ian W. Fletcher, Martin P. Seah

A complication and barrier to wider uptake of SIMS, especially for organic materials, is the complexity of the mass spectrum. The G-SIMS method (from gentle-SIMS) was developed to simplify the spectra and provide direct interpretation based on the physics and chemistry of the SIMS process rather than on statistical analysis techniques such as principal component analysis or library matching methods.

Molecular imaging by mass spectrometry: application to forensics

Tiffany Porta, Emmanuel Varesio, Thomas Kraemer, Gérard Hopfgartner

After an introduction to MALDI, DESI and SIMS, the authors describe their main applications in forensics, as well as the advantages provided in terms of sample preparation over approaches routinely used in toxicological laboratories.

Secondary neutral mass spectrometry: a powerful technique for quantitative elemental and depth profiling analyses of nanostructures

Kálmán Vad, Attila Csik, Gábor A. Langer

The purpose of this article is to give a comparative description of two methods applying ion-beam sputtering in materials research: secondary ion and neutral mass spectrometries (SIMS and SNMS). We shall illustrate the application of the latter by reports on a compositional analysis of perovskite oxides and on an investigation of nanoscaled multilayer structures.

Combined infrared and visible spectroscopic ellipsometry study of thin polymer layers

K. Hinrichs, K. J. Eichhorn

Thin polymer layers on solid substrates are of high technological importance due to their increasing potential for applications in electronics, sensors, nanotechnology and biotechnology. Appropriate characterisation methods are necessary for the design and analysis of devices made using such materials. This review article focuses upon presenting the many analytical possibilities for quantitative evaluation of the optical constants and thickness of polymer layers by combined application of spectroscopic ellipsometry (SE) in the visible (vis) and infrared (IR) spectral range.
