intensity ratio of the output X-ray intensity to the incident X-ray intensity). This is because the FWHM of the rocking curve of a perfect crystal can be predicted based on dynamical diffraction theory, which states that the FWHM is related to the structure factor of the crystal and is...
Typically, after ball milling of salt mixtures (e.g., CoCl2-NaCl in ∼1/1wt %) for 0.5 h, the intermediate product was immediately characterized by X-ray diffraction (XRD). Interestingly, when the solvent was NaCl (a = 5.67 Å), the XRD exhibited a group of typical peaks (27.3°...
which is much more accurate and effective than the optical diffraction limit. It uses a probe for measuring and collection of data involves touching the surface that has the probe. An image is formed when the scanning probe microscope raster-scans the probe over a section of the sample, measur...

Here, we will only con- sider systems with one plane of symmetry as it is the most common category. The two other symmetry categories can be treated similarly. To describe the transverse ray aberrations (see Fig. 1) in the case of an optical system with the x-z plane of symmetry we ...

There are numerous studies on the growth of planar films onsp2-bonded two-dimensional (2D) layered materials. However, it has been challenging to grow single-crystalline films on 2D materials due to the extremely low surface energy. Recently, buffer-assisted growth of crystalline films on 2D lay...
