Physical properties of oxide thin films and heterostructures

氧化物薄膜和异质结构的物理性质 * 拟议的研究将探索氧化物材料和复杂的结构，基于氧化物，呈现受强电子相关性影响的物理性质。所有的项目都涉及氧化物薄膜的生长，如单层或由几种材料制成的异质结构（多层）。我们将创造新的结构，旨在包围这些不同的氧化物的电子相，并研究它们的竞争，共存，甚至在新的电子状态的物质出现他们的合作。总之，这些项目将集中在：1）超导电子掺杂（n型）铜酸盐，通过探测针对高温超导性的未知起源的特性; 2）磁性氧化物显示出大的磁热效应，对磁制冷应用非常感兴趣。这些项目将有助于加深我们对氧化物中强电子-电子相互作用引起的物质新电子相的理解。若干项目还可有助于开发制造和设计装置的新专门知识，以用于纳米技术、电子、电信、医学、安全以及能源运输和储存等领域的潜在应用。

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.
