XRD

​​X-ray diffraction (XRD) analysis is a powerful tool used for understanding the crystallographic structure of materials. It is widely used to identify phases and perform quantitative analysis. It is also used to determine the crystal structures of new compounds. Additional information such as residual stress, crystal quality, and thin film quality can be determined from advanced X-ray diffraction based techniques. 

Our facility covers a wide range of X-ray diffraction based characterization techniques to handle different types of materials. We also host a variety of analytical software to aid the analysis of X-ray diffraction data.
