WebThe Scherrer equation is limited to nano-scale crystallites, or more-strictly, the coherently scattering domain size, which can be smaller than the crystallite size (due to factors mentioned below). It is not applicable to grains larger than about 0.1 to 0.2 μm, which precludes those observed in most metallographicand ceramographicmicrostructures. WebThe crystallinity properties of perovskite influence their optoelectrical performance in solar cell applications. We optimized the grain shape and crystallinity of perovskite film by annealing treatment from 130 to 170 °C under high humidity (relative humidity of 70%). We found that the grain size, grain interface, and grain morphology of the perovskite …
WebApr 13, 2024 · Moreover, the samples with 0.10 Al content showed a smaller crystallite size than the un-doped samples and the samples with 0.05 Al. A decrease in crystallite size means an increase in the area fraction of grain boundaries which in turn acts as strong barriers to dislocation motions and improves the hardness/strength of the sample … Web2.3K views 2 years ago Origin software for data analysis Calculation of crystallites size and microstrain through the Williamson- Hall plot method is the best idea.
