Looking beyond Limitations of Diffraction Methods of Structural Analysis of Nanocrystalline Materials

In this work we discuss how to learn about the real atomic structure of nanocrystalline materials without misinterpreting the results of powder diffraction experiments. We discuss implications of nano-size on powder diffractograms based on some theoretical models of nanograins. Examples of experimental studies on nanocrystalline diamond and SiC are demonstrated.
