The diffraction pattern is a product of the unique crystal structure of a material • The crystal structure describes the atomic arrangement of a material. • The crystal structure determines the position and intensity of the diffraction peaks in an X-ray scattering pattern.
An X-ray source is used to irradiate the specimen and to cause the elements in the specimen to emit (or fluoresce) their characteristic X-rays. A detection system (wavelength dispersive) is used to measure the peaks of the emitted X-rays for qual/quant measurements of the elements and their amounts.
X-ray diffraction (XRD) is a versatile, non-destructive analytical method to analyze material properties like phase composition, structure, texture and many more of powder samples, solid samples or even liquid samples.
Sin2(ψ) XRD method. Can be done with any detector, but 2D detector allows for much faster data collection. Collect a series of measurements of a diffraction peak at different sample rotation and tilt angles and assess peak position change. Fit models to the data to calculate the stress tensor value.
Fortunately, X-ray difraction (XRD) provides such a tool, and is arguably the most useful and versatile technique in the characterisation of thin films.1 XRD can be used to obtain the following infor-mation on thin films: Crystalline phase and lattice parameters. Degree of crystallinity.
1 Principles of X-ray Diffraction. Diffraction effects are observed when electromagnetic radiation impinges on peri-odic structures with geometrical variations on the length scale of the wavelength of the radiation.
