Best Practices for Thin Film XRD Sample Preparation: Substrate Cleaning Procedures: Start by thoroughly cleaning the substrate surface to remove any contaminants or residues that could interfere with thin film deposition or XRD analysis.Use appropriate solvents, such as acetone or isopropyl …

Principle of XRD. The principle of X-ray diffraction (XRD) is based on the constructive interference of monochromatic X-rays and a crystalline sample. X-rays are electromagnetic radiation with a wavelength that is similar to the interatomic spacing in crystals. When a beam of X-rays is directed at a crystal, the X-rays interact with the …
