氧化物材料，基于氧化物的界面和异质结构：寻找新的物质状态。提出的研究将探索氧化物材料和基于氧化物的复杂结构，这些材料和结构的物理性质受到强电子相互作用的影响。所有的项目都涉及到由多种材料制成的单层或异质结构（多层）氧化薄膜的生长。我们将创造新的结构来缠绕这些不同氧化物的电子相，并研究它们之间的竞争、共存甚至合作，从而产生新的物质电子态。综上所述，项目将重点关注：1)高温超导体与各种氧化物之间的异质结构；2)电子掺杂铜高温超导体与常规超导体之间的约瑟夫森结，探索铜酸盐中超导性的未知来源；3)铁磁性和铁电性相结合的多铁性材料。这些项目将有助于加深我们对由于氧化物和这些氧化物之间的界面中强电子-电子相互作用而出现的新型物质电子相的理解。有几个项目还可以促进在制造和设计设备方面发展新的专门知识，这些设备可能应用于纳米技术、电子、电信、医学、安全以及能源运输和储存等领域。

Oxide materials, Oxide-based Interfaces and Heterostructures: the search for novel states of matterThe proposed research will explore oxide materials and complex structures based on oxides that present physical properties influenced by the strong electronic interactions. All the projects involve the growth of oxide thin films as monolayers or heterostructures (multilayers) made of several materials. We will create new structures designed to entwine the electronic phases of these various oxides and study their competition, their coexistence and even their cooperation in the emergence of novel electronic states of matter. In summary, the projects will focus on: 1) heterostructures between high temperature superconductors and various oxides; 2) Josephson junctions between electron-doped cuprate high temperature superconductors and conventional superconductors to probe the still unknown origin of superconductivity in cuprates; 3) multiferroic materials combining ferromagnetism and ferroelectricity. These projects will help deepen our understanding of emerging novel electronic phases of matter due to strong electron-electron interactions in oxides and interfaces between these oxides. Several projects could also contribute to the development of a new expertise in the fabrication and design of devices for potential applications in the fields of nanotechnology, electronics, telecommunications, medical science, security and energy transport and storage.
