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:

物质的基本特性由于受限量的量子效应而发生巨大变化。这是纳米科学的基础，也是生产高级材料和设备的基石。对这些改进的材料和设备的追求很大程度上取决于在原子规模上改变其建筑，组成和关键特性的现有和新方法。在我们的小组中，我们专注于获得对复杂材料及其界面的原子级行为的见解。我们采用了纳米材料生长的先进方法，例如离子束植入和分子束外延（MBE）。我们依靠表面和界面表征，具有子纳米的深度分辨率（例如中能离子散射，MEI）和原子侧分辨率，以建立我们对表面和界面过程中过程的基本理解。我们将这些知识作为理解设备性能的基础。拟议的研究计划可以分为两个相互联系的主题：
