Plasma-Induced 2D Electron Transport at Hetero-Phase Titanium Oxide Interface.

ABSTRACT: Interfaces of metal oxide heterojunctions display a variety of intriguing physical properties that enable novel applications in spintronics, quantum information, neuromorphic computing, and high-temperature superconductivity. One such LaAlO₃ /SrTiO₃ (LAO/STO) heterojunction hosts a 2D electron liquid (2DEL) presenting remarkable 2D superconductivity and magnetism. However, these remarkable properties emerge only at very low temperatures, while the heterostructure fabrication is challenging even at the laboratory scale, thus impeding practical applications. Here, a novel plasma-enabled fabrication concept is presented to develop the TiO₂ /Ti₃ O₄ hetero-phase bilayer with a 2DEL that exhibits features of a weakly localized Fermi liquid e
