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.
