Structure and Properties Relationships in Nanoscale Materials

这项建议描述了一项雄心勃勃的研究计划，该计划与了解纳米材料的性质、化学键、原子结构和电子结构之间的关系有关。计划中的研究计划旨在了解掺杂原子对复杂材料性能的作用及其对电子结构的影响，低至原子水平的电子结构，界面的详细原子结构，界面性质引起的局部应变引起的结构和性能变化，以及它们对材料相稳定性的作用。这项工作将通过对基于高温超导体和半导体材料的复合氧化物薄膜的详细研究来演示，这些材料用于成像、传感器和探测器。该计划的第二个组成部分旨在探索新的混合材料体系结构，利用材料中电子气的共振耦合，导致这一仍然基础的领域的更广泛应用，并发现自然界中不存在的人造材料。

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.
