This is the most critical concept for understanding electrical and optical properties.
Materials Engineers use XRD to identify unknown phases in a sample. Every material has a unique "fingerprint" of diffraction peaks. This is non-destructive verification of material purity and phase composition. This is the most critical concept for understanding
