Architectures and profiling of nanomaterials with ion beams

由于受限粒子中的量子效应，物质的基本性质发生了巨大的变化。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很大程度上依赖于现有的和新的方法，即在原子尺度上改变其结构、组成和关键性质。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。我们采用了先进的纳米材料生长方法，如离子束注入和分子束外延(MBE)。我们依靠亚纳米深度分辨率的表面和界面表征(如中能离子散射，MEI)和原子的横向分辨率来建立我们对表面和界面过程的基本理解。我们使用这些知识作为了解设备性能的基础。拟议的研究方案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:
