Structure and Properties Relationships in Nanoscale Materials

This proposal describes an ambitious research program related to the understanding of the relationship between properties, chemical bonding, atomic structure and electronic structure in nanoscale materials. The planned research program aims to understand the role of dopant atoms on complex materials properties and their effect on the electronic structure down to the atomic level, the detailed atomic structure of interfaces, the changes in structure and properties induced by local strain due to the nature of interfaces and their role on the phase stability of materials. This work will be demonstrated through detailed investigations of complex oxides thin films based on high-temperature superconductors and semiconducting materials used for imaging, sensors and detectors. A second component of the program aims to explore new hybrid material architectures exploiting the coupling of resonances of the electron gas in materials, leading to broader application of this still-fundamental field and to the discovery of artificial materials that do not exist in nature.
