Fwhm coefficient
WebApr 11, 2024 · The film FWHM was obtained by calculations from a Lorentz curve fit in the experimental data between 34° and 38°. Among them, FWHM in fifteen sets of experiments is between 0.1°–0.506°. We observed that experiment S3 has the minimum FWHM value, indicating that the AlN film has better crystallinity under this parameter. WebThe refractive index n = 1.
