氧化薄膜和异质结构的物理性质***提出的研究将探索基于氧化物的氧化材料和复杂结构，其物理性质受强电子相关性的影响。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，这些项目将集中在：1)通过探测高温超导性的不明起源的性质来探测超导电子掺杂（n型）铜酸盐；2)磁性氧化物具有较大的磁热效应，在磁制冷应用中具有重要意义。这些项目将有助于加深我们对氧化物中由强电子-电子相互作用引起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。

Physical properties of oxide thin films and heterostructures***The proposed research will explore oxide materials and complex structures based on oxides that present physical properties influenced by the strong electronic correlations. 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) superconducting electron-doped (n-type) cuprates by probing properties targeting the unexplained origin of high temperature superconductivity; 2) magnetic oxides showing large magnetocaloric effect, of great interest for magnetic refrigeration applications. These projects will help deepen our understanding of emerging novel electronic phases of matter induced by strong electron-electron interactions in 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.
