      Please Arfa if you know anyone who expert on XPS and NEXAS and RPES and STM please let me know I feel struggling with my work.

      @mashaelalotaibi8062 Okay, sure. I recommend asking questions on *researchgate * will definitely help you. There are many quality researchers on RG.

    Sir I have tested polypyrrole which is amorphous in nature I got crystalline size of 0.03 nm is it ok

      This video basically shows that the XRD pattern for nanomaterials (size ~ 1 to 100 nm) AND amorphous materials are exactly *SAME*
      We can't differentiate between the two graphs , therefore, we need additional characterization techniques to confirm whether the materials are amorphous or Nano.
      In your case, the crystallite size is *extremely SMALL*
      🤔 How is it possible??

      I am also asking same question

      @@manashjyotidas3748 I don't understand your question?
      How do you calculate the crystallite size?

      I have used the scherrer formula and got 0.03 nm should I have to convert FWHM value to radian

      @manashjyotidas3748 Yes, the 2theta must be in radian
