Structure and Properties Relationships in Nanoscale Materials

本提案描述了一个雄心勃勃的研究计划，涉及对纳米材料的性质、化学键、原子结构和电子结构之间关系的理解。计划的研究项目旨在了解掺杂原子对复杂材料性能的作用及其对原子水平电子结构的影响，界面的详细原子结构，由于界面性质引起的局部应变引起的结构和性能的变化及其对材料相稳定性的作用。这项工作将通过详细研究基于高温超导体和用于成像、传感器和探测器的半导体材料的复杂氧化物薄膜来证明。该项目的第二个组成部分旨在探索利用材料中电子气体共振耦合的新型混合材料架构，从而使这一仍然是基础的领域得到更广泛的应用，并发现自然界中不存在的人工材料。

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.
