I am working with ZnO NANOWIRES which has prefered orientation on 002 planes. I've been doing Rietveld refinement of X-ray data using MAUD and I have read that for epitaxial ZnO, one can use the standard functions in MUAD and change some parameters ( phi, omega,... etc.). Well, whatever changes I make it makes the fitting worse. Can anyone help? what should I do to fit the highest peak in ZnO NANOWIRES in MAUD?
Notes/
I am uploading the cif. file and an example of my XRD result.
Zhang, R. H., E. B. Slamovich, and C. A. Handwerker. "Controlling growth rate anisotropy for formation of continuous ZnO thin films from seeded substrates." Nanotechnology 24, no. 19 (2013): 195603.
MAUD is not a very appreciated software for Rietveld refinement. For beginners or for basic profile fitting, it works well; but if you want to fit multiphase materials, complex structures, preferred orientations, strained materials, magnetic and nanomaterials, non-stoichiometric compounds etc; you might go through problems for precise fitting. In fact, high impact journals and renowned journals of physics prefer FULLPROF more.
I'll personally suggest FULLPROF, it is a bit harder, but it is the most powerful software, which will offer you 20-30 parameters for finest refinement.
There are a number of tutorials present in youtube as well, you can learn it by a week.
Souvik Bhattacharjee Sir, can you please attach a few links to start learning FULLPROF?
Thank you.

Start with these two videos. Then you'll get more video-suggestions on youtube. FULLPROF and Vesta both are free software. Download them, and start with a standard (simple) material. Don't begin with complicated materials at the first try.
