Coupling Lattice Instabilities Across the Interface in Ultrathin Oxide Heterostructures
Coupling Lattice Instabilities Across the Interface in Ultrathin Oxide Heterostructures
Oxide heterointerfaces constitute a rich platform for realizing novel functionalities in condensed matter. A key aspect is the strong link between structural and electronic properties, which can be modified by interfacing materials with distinct lattice symmetries. Here, we determine the effect of the cubic-tetragonal distortion of SrTiO3 on the electronic …
