Anisotropies in electronic transportations conventionally originate from thenature of low symmetries in crystal structures, and were not anticipated forperovskite oxides, the crystal asymmetricity of which is far below, e.g. vander Waals or topological crystal. Beyond conventional expectations, herein wedemonstrate pronounced anisotropies in the inter-band coulomb repulsiondominated electronic transportation behaviors under low-dimensional confinementfor the perovskite family of rare-earth nickelates (ReNiO3). From one aspect,imparting bi-axial interfacial strains upon various lattice planes results inextrinsic anisotropies in the abrupt orbital transitions of ReNiO3, and theirmetal to insulator transition behaviors that elevates the transitiontemperature beyond the existing merit. From the other aspect, the in-planeorbital entropy associated to the in-plane symmetry of the NiO6 octahedronwithin ReNiO3 causes intrinsic anisotropies for the gradually orbitaltransition with temperature to further improve their thermistor transportationproperties. The present work unveils the overlooked role of the electronicorbital directionality within low dimensional correlated perovskites that cantrigger anisotropic transportation behaviors, in spite of their relativelysymmetric crystal structures. Establishing anisotropic transportationsintegrating the electron correlation and quantum confinement effects will bringin a new freedom for achieving further improvement in transportation propertiesof multi-functional perovskite oxides.
