The lattice response of a prototype Mott insulator, SmTiO_{3}, to hole doping is investigated with atomic-scale spatial resolution. SmTiO_{3} films are doped with Sr on the Sm site with concentrations that span the insulating and metallic sides of the filling-controlled Mott metal-insulator transition (MIT). The GdFeO_{3}-type distortions are investigated using an atomic resolution scanning transmission electron microscopy technique that can resolve small lattice distortions with picometer… Expand
Lattice relaxations around individual dopant atoms in SrTi O 3
The local atomic structure around individual dopant atoms can directly influence the electronic properties of a doped material. Here, we use quantitative scanning transmission electron microscopy toExpand
Universal superconducting precursor in perovskite-based oxides
A pivotal challenge posed by unconventional superconductors is to unravel how superconductivity emerges upon cooling from the generally complex normal state. Some of the most prominent unconventionalExpand
Universal superconducting precursor in three classes of unconventional superconductors
TLDR
This work uses nonlinear magnetic response, a probe that is uniquely sensitive to the superconducting precursor, to uncover remarkable universal behaviour in three distinct classes of oxide superconductors: strontium titanate,strontium ruthenate, and the cuprate high-Tc materials. Expand
Sub-Unit Cell Spatial Resolution of Phase and Polarization Mapping in Scanning Electron Diffraction
Diffraction analysis in four dimensional scanning transmission electron microscopy now enables the mapping of local structures including symmetry, strain, and polarization of materials. However,Expand
Two-component electronic phase separation in the doped Mott insulator Y$_{1-x}$Ca$_{x}$TiO$_{3}$
One of the major puzzles in condensed matter physics has been the observation of a Mottinsulating state away from half-filling. The filling-controlled Mott insulator-metal transition, induced viaExpand
