Intensity corrections for grazing-incidence X-ray diffraction of thin films using static area detectors

Area of Science:

• Materials Science
• Crystallography
• Surface Science

Background:

• Grazing-incidence X-ray diffraction (GIXD) is vital for thin film analysis.
• Accurate peak intensity extraction is essential for determining atomic positions.
• Existing GIXD data analysis lacks comprehensive correction factor compilation.

Purpose of the Study:

• To systematically compile and derive analytical formulae for GIXD intensity corrections.
• To provide corrections applicable to modern GIXD setups with static area detectors.
• To improve the accuracy of crystallographic and textural quantification from thin film GIXD data.

Main Methods:

• Derivation of analytical formulae for polarization, solid-angle, absorption, transmission, and Lorentz corrections.
• Application of derived corrections to GIXD data from various sample textures (single crystal, random, oriented crystallites).
• Comparison of corrected integrated peak intensities with literature single-crystal diffraction data.

Main Results:

• A systematic compilation of necessary intensity corrections for GIXD is presented.
• The derived formulae were successfully applied to diverse thin film samples.
• Accurate intensity corrections were demonstrated to yield reliable peak intensities.

Conclusions:

• The developed intensity correction framework enhances the quality of crystal structure solutions from thin films.
• Accurate phase and texture quantification from GIXD measurements are achievable with these corrections.
• This work provides a valuable resource for researchers utilizing GIXD for thin film characterization.
