Preparation and characterization of Mg-doped CaCu3Ti4O12 thin films

Green hydrothermally synthesized ultrathin Mg-doped CuO nanoflakes: a structural, electrical and dielectric study

“…1(g) illustrates that the unit cell volume ( V ) decreases with increasing the Mg concentration, which can be attributed to the difference between the ionic radii of Cu 2+ (0.73 Å) and Mg 2+ (0.72 Å) ions. 49,51 The crystallite size ( D ) was estimated from the dominant diffraction peak (111̄) using the Debye–Scherrer equation: 52 where K is the shape factor (taken to be 0.9), λ is the wavelength of the incident X-ray beams (1.5406 Å), β hkl is the full width at the half maximum (FWHM) and θ is the diffraction angle. As shown in Fig.…”
