“…µXRD techniques are currently routinely employing beam sizes of a few µm for polymer sample thicknesses down to a few µm. Sub-µm beams, are, however, becoming available and ≤100 nm beams have been reported [9,10,11]. Those techniques usually require little preparation of the sample, in contrast with transmission electron diffraction/imaging (TED/TEM) techniques which provide beam sizes down to about 10 nm but require elaborate embedding and sectioning techniques [12,13].…”
