Extreme Reconfigurable Nanoelectronics at the CaZrO3/SrTiO3 Interface

ORAL

Abstract

The metal-insulator transition at the interface between polar LaAlO3 (LAO) and non-polar SrTiO3 (STO) can be controlled using conductive atomic force microscopy (c-AFM) lithography. Here we report extreme nanoscale control over the CaZrO3/SrTiO3 (CZO/STO) interface, a nonpolar 2DEG system which is formed by strain-induced polarization. Ultra-thin (1 to 3 nm wide) nanostructures can be realized at the CZO/STO interface at room temperatures, and superconducting quasi-1D and 2D structures of CZO/STO are investigated at cryogenic temperatures. Combining the versatility of c-AFM lithography with the rich physics at complex oxide interfaces, reconfigurable nanoelectronics paves new ways to investigate the correlated spin, charge and orbital degree of freedoms.
