Architectures and profiling of nanomaterials with ion beams

物质的基本性质由于受限粒子中的量子效应而发生急剧变化。这是纳米科学的基础，也是生产先进材料和设备的基石。对这些改进材料和器件的追求强烈依赖于在原子尺度上改变其结构、组成和关键特性的现有和新方法。在我们的团队中，我们专注于深入了解复杂材料及其界面的原子尺度行为。我们采用先进的纳米材料生长方法，如离子束注入和分子束外延（MBE）。我们依靠表面和界面表征与亚纳米深度分辨率（如中能离子散射，MEIS），和原子的横向分辨率，建立我们的基本理解的过程在表面和界面。我们将这些知识作为理解器件性能的基础。拟议的研究计划可分为两个相互关联的主题：

The fundamental properties of matter change dramatically due to quantum effects in confined particles. This is the foundation of nanoscience and a cornerstone for the production of advanced materials and devices. The pursuit of these improved materials and devices strongly depends on existing and new methods of changing their architecture, composition and key properties at the atomic scale. In our group we focus on gaining insights into the atomic-scale behavior of complex materials and their interfaces. We employ advanced methods of nanomaterials growth, such as ion beam implantation and molecular beam epitaxy (MBE). We rely on surface and interface characterization with sub-nanometer depth resolution (such as medium energy ion scattering, MEIS), and the atomic lateral resolution to build our fundamental understanding of processes at the surfaces and interface. We use this knowledge as a foundation for understanding device performance. The proposed research program may be divided into two interconnected themes:
