Abstract

The extended project as the existing one aims to investigate, control and exploit the properties of interfaces between isostructural functional oxides for the realization of new nanosized electronic and optoelectronic devices. New participants will contribute to the characterization and understanding of physical properties of interfaces made of perovskite materials. In particular high frequency dynamical properties, fluctuation phenomena and dielectric spectrum will be carefully studied. The integration of these aspects in NANOXIDE will open fields of crucial importance for the high frequency operation of some of the proposed devices. Nonlinear picosecond electronic transport properties and nonequilibrium shot noise emission in nanostructured interfaces will be investigated in details. The HTS Josephson junctions with critical frequency increased over 1 THz grown on buffered sapphire or tilted NdGaO3 substrates will be realized and investigated. Studies of field effect between ferroelectric and conducting films will be performed in order to extract important information about charge carrier density at nanometer scale. In this respect, the heterostructures with different intermediate layers sandwiched between epitaxial HTS films, manganites or ruthenates will be realized and extensively studied. New participants will contribute also in nanostructuring of engineered interfaces for realization of nanodevices which exploit the high frequency low noise properties of HTS/HTS and the specific nonlinearity of Antiferromagnetic-Superconductor interfaces. Additional deliverables of TTC will be magnetic and superconducting thin film integrated devices suitable for high speed electronics including THz frequency range.
