Picometer polar atomic displacements in strontium titanate determined by resonant X-ray diffraction

It is a challenge to measure changes in the crystal structures in picometer scale and the associated phase. Here the authors demonstrate the lattice expansion and polar distortions of oxygen deficient SrTiO3 using a resonance X-ray scattering technique.
