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:

由于受限粒子中的量子效应，物质的基本特性发生了巨大的变化。这是纳米科学的基础，也是先进材料和设备生产的基石。对这些改进材料和设备的追求很大程度上取决于在原子尺度上改变其结构、成分和关键特性的现有方法和新方法。在我们的小组中，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，例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（例如中能离子散射，MEIS）和原子横向分辨率的表面和界面表征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。拟议的研究计划可分为两个相互关联的主题：
