The reasons for peak shift in XRD (X-ray diffraction) usually involve changes in the properties of the sample itself or the influence of experimental conditions, which can be analyzed from the following aspects: 1. Sample factors 1.1 Residual stress or lattice strain Residual stress: Residual stress inside the material (such as compressive stress or tensile stress) can cause changes in the lattice...

What Size Do XRD, SEM and TEM Actually Measure? X-ray diffraction (XRD) records how a crystal scatters X-rays, conventionally with the diffraction angle 2θ on the horizontal axis and diffracted intensity on the vertical axis. A periodic arrangement of atoms produces diffraction peaks, and the width of a peak is related to the distance over which that arrangement remains coherent. The coherent doma...
