Crystallite size scherrer equation

WebJun 1, 2024 · The observation that the traditional W-H method under-estimates both the crystallite size and the strain value forced us to investigate the magnitude of these under-estimations. In Fig. 3 (c) we show a plot of Scherrer size, DS, against the W-H size, DW-H, which gives D S = ( 1.71 ± 0.42) D W - H - ( 1.31 ± 2.21) when intercept is considered. WebApr 15, 2024 · The crystalline size deduced from the Williamson-Hall plot (i.e., x = 1.559 nm) is slightly larger than the average value of 0.9639 nm derived from Scherrer’s equation. The difference may be aligned with the fact that Scherrer’s equation operates on the assumption that the internal stress is zero and does not consider broadening explicitly.
