    Graduate XRD FWHM, debye-scherrer's formula & AFM surface morphology

    Hi guys, I have an question about the correlation between grain size caculated from debye-scherrer and the AFM results for my AlN epi layer samples. From my AFM results, the trend of grain size of three samples are getting smaller( around 200-10 nm range among three samples). but the FWHM of...
