项目摘要

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.

氧化物材料、氧化物界面和异质结构：寻找新的物质态拟议的研究将探索氧化物材料和基于氧化物的复杂结构，这些氧化物呈现出受强电子相互作用影响的物理特性。所有项目都涉及由多种材料制成的单层或异质结构（多层）氧化物薄膜的生长。我们将创建新的结构来缠绕这些不同氧化物的电子相，并研究它们的竞争、共存，甚至它们在新型物质电子态出现中的合作。综上所述，该项目将重点关注：1）高温超导体与各种氧化物之间的异质结构； 2）电子掺杂铜酸盐高温超导体和传统超导体之间的约瑟夫森结，以探索铜酸盐中超导性的仍然未知的起源； 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中以及这些氧化物之间的界面中强烈的电子-电子相互作用而出现的新型物质电子相的理解。一些项目还可以有助于开发设备制造和设计方面的新专业知识，以用于纳米技术、电子、电信、医学、安全以及能源运输和存储领域的潜在应用。
