The reasons for peak shift in XRD (X-ray diffraction) usually involve changes in the properties of the sample itself or the influence of experimental conditions, which can be analyzed from the following aspects: 1. Sample factors 1.1 Residual stress or lattice strain Residual stress: Residual stress inside the material (such as compressive stress or tensile stress) can cause changes in the lattice...

The major limitations on TEM performance are spherical aberration (also known as aberration), chromatic aberration, and astigmatism. The spherical aberration and chromatic aberration limit the resolution of traditional TEM. Both of these defects are inevitable when using static rotational symmetric electromagnetic fields. Ball aberration is the most important factor determining the performance of ...
