You can use XRD to determine
• Phase Composition of a Sample
–Quantitative Phase Analysis: determine the relative amounts of phases in a mixture by referencing the relative peak intensities
• Unit cell lattice parameters and Bravais lattice symmetry
–Index peak positions
–Lattice parameters can vary as a function of, and therefore give you information about, alloying, doping, solid solutions, strains, etc.
• Residual Strain (macrostrain)
• Crystal Structure
–By Rietveld refinement of the entire diffraction pattern
• Epitaxy/Texture/Orientation
• Crystallite Size and Microstrain
–Indicated by peak broadening
–Other defects (stacking faults, etc.) can be measured by analysis of peak shapes and peak width
• We have in-situ capabilities, too (evaluate all properties above as a function of time, temperature, and gas environment)
