Structural inhomogeneity in oxide superconductors
It has long been known that some of the most prominent complex oxides display significant structural and electronic inhomogeneity. The nature and role of this inhomogeneity, however, has been intensively debated. In this talk, I will present new insights into intrinsic structural inhomogeneity from state-of-the-art diffuse neutron and x-ray scattering experiments, in two representative material systems: the cuprate high- temperature superconductors [1] and strontium titanate [2]. Our ongoing, systematic studies of cuprate local structure reveal intriguing short- range correlated disorder ; in strontium titanate, we have been able to manipulate extended defects using plastic deformation, with striking effects on the electronic subsystem. These results show that structural inhomogeneity is an essential ingredient in the physics of these oxides, and that it can be used to tune their electronic properties, with implications for a wide range of important quantum materials.
