I What is the difference between regular Xray diffraction and high resolution X-ray diffraction?

  1. May 17, 2017 #1
    Hello
    What does it mean when people say high resolution xray diffraction? What is the difference between regular Xray diffraction and high resolution X-ray diffraction?

    Thank you

    Is there a such thing as "regular" X-ray diffraction?

    It's possible that the hi-rez is simply describing that X-ray diffraction is higher-rez than other forms of diffraction (say, visible light). This because X-rays are higher frequency.

    The resolution in this case refers to the angular resolution of the system, which in turn translates into how precise the crystal spacing can be measured. The HRXRD is usually used to study deviations from the ideal crystal structure, the structure of individual diffraction peaks, defects and probably other things. It is used in characterization of thin layers, which may have distorted structure. As I understand, it is just a matter of more sophisticated components (monochromators, windows, mirrors, mechanics) but the principle is the same as for any XRD.
