Strongly correlated oxide materials exhibit a wide range of properties and recently many new and exciting results have been discovered as a result interfaces between oxides grown in thin film heterostructures, including 2D electron gasses, superconductivity, and new magnetic phases not seen in the bulk state. The rare-earth nickelates (RNiO3) exhibit a metal to insulator transition with varying temperature; this transition can be tuned by varying the rare earth, substrate, and film thickness.
Oxide materials also play an important role as dielectrics. The Martinis group at UCSB is making great advances in the development of superconducting resonators, which are used to construct qubits for quantum computing. The interface between the superconductor and the dielectric is a source of de-coherence for the qubits, we are growing and characterizing this interface in-situ to understand and limit the sources of this de-coherence.
