WebApr 9, 2024 · In particular, over the substrate temperature range of 25 °C to 200 °C, the crystallite size of the samples decreased from 36.4 nm to 18.2 nm with increasing FWHM values. On the other hand, the grain size analyzed in the FE-SEM images in this temperature range improved from 45 nm to 54 nm. WebMay 18, 2015 · The average crystallite size ( D) of each sample is estimated from the well-known Scherrer’s equation, which is given below: D = k λ β hkl cos θ hkl (3) Where k is the shape factor, λ is the wavelength of X-Ray, θhkl is the Bragg angle and βhkl is the corrected full width at half maximum ( FWHM ).
