In the case of nearly perfect semiconductor layers (as AlGaAs on GaAs), the experimental data of X-ray Diffraction are well simulated using the Dynamical Theory of X-ray Diffraction. In the case of AlGaN and InGaN layers, intensity of their XRD peaks depend very strongly on the ...
X-ray diffraction (XRD) analysis was conducted to examine the crystallinity and crystal orientation of the 2D perovskite films. As illustrated in Fig. 2a, all films exhibit distinctive diffraction peaks at 14.2° and 28.5°, attributed to the (111) and (202) crystal planes, respectively31. ...

X-ray diffraction showed all diffraction peaks of the anatase phase well (Fig.1E). The characteristic peak of the anatase phase was 2Ɵ = 25.334. Several sharp peaks are observed in the 2Ɵ range at 20–80°. The sharp peaks in the 2Ɵ range were 25.12°, 38.25°, 48.10°,...
The result reveals that the distribution is almost uniform (variation in PL intensity is ~0.1% in same order of magnitude) from position A to B in both the cases except the two broad peaks originating from the both edges of the bundle as shown in Fig. 3c. Usually, the PL intensity ...
Kβ/ Kα intensity ratios of Zn were measured at a photon excitation energy of 59.5 keV using a high-resolution Si(Li) detector for several thickness at different pressure. Present results were compared with theoretical data and other experimental values. The results were in good agreement theore...

This is supported by the fact that there were no extra peaks of impurities related to ZnO or Al2O3. The same phases without impurities were observed for all Pb2+doped samples at the range of 0–5 mol%. Thus, it is highly believed that the Pb2+ ions were fully incorporated into the...
The energy level of the defect states are schematically shown valence band with a luminance with subpeaks of in Fig. 6. B1HfO2 and B 2 HfO2 , respec- Additionally, the annealing temperature dependence of the integrated blue PL intensity was shown in Fig. 7. In most light-emission ...
The method utilizes the X-ray intensity ratios of Kα/Kβ or Lα/Lβ peaks (or the ratio of these peaks) for selected elements present in multi-layered objects of various materials (Au alloys, gilded Cu, gilded Ag, gilded Pb, Ag–Au Tumbaga, stone surfaces with protective treatments, ...
