am i supposed to strip out Ka2 for rietveld refinement? also, could you please check if my steps/logic is right?

hi,

the first pic is undoped material and im trying to refine it.

we have an expert in refinement but they do not teach things in detail.

so, I am doping little amounts of C into AB2. since it doesn't affect the structure much, I'd be using Rietveld refinement to compare the lattice parameters.

is this correct?

also, in the C doped AB2 (Next Pic) there are some peaks that I haven't found in the database (PDF5). the green and blue peaks cannot be considered, right? Since not all the peaks correspond with my xrd.

Can we please stop with low effort ‘when will I hear back from professors’ kinda posts?

There are other subReddits such as r/GradAdmissions for this matter.

Deadlines are usually mentioned in the application portal so please use that.

And if you’re using AI to format the post, consider asking the questions to AI because most of these questions are already answered in other posts.

Put some efforts in your application. Your grades, IELTS score, everything matters! But most importantly, it’s your research experience that’ll grant you the admission and funding.
