The fascinating physical properties of functional crystalline materials are strictly linked to symmetry and/or compositional inhomogeneities at the nanoscale and sometimes at even larger length scales, caused by high defect concentrations and/or strong electron correlation and/or structural reconstruction at the surface of nanoparticles. Therefore, a meaningful structural characterisation should encompass short-, medium, and long range investigations.
The so-called Pair Distribution Function (PDF), that is the real space analysis of diffraction data, is emerging as a powerful technique to achieve a complete and accurate structural picture at all the length scales.
In this friendly talk, after an introduction to the technique, I will present some applications of PDF to material science cases.
Examples will include i) highly defective oxides, where defect clusters hierarchically self-organise into nanodomains; ii) nanomaterials; iii) perovskite oxides displaying symmetry breaks at the local scale.
