What is the exact reason crystal size small despite of the sem shows big faceted paprticles?

The question is why we have very small crystal size in XRD but in SEM we can observe big faceted crystals, For example perhaps the faceted particles may not be single crystal?

What is the best substrate for exfoliating few layers of hexagonal boron nitride (hBN) using traditional scotch tape method?

Unlike graphene, it is usually very difficult to exfoliate few layers (~10 nm thick) of hBN on SiO2 substrate due to lip-lip interaction at the edges. Au substrates have been proven very useful...
