The discovery and control of novel quantum materials are essential to the progress of modern technology. These materials frequently show complex behaviours that demand multiple, complementary techniques to fully understand their properties. For example, the electronic band structure, which is central to understanding emerging quantum materials, is typically investigated using angle-resolved photoemission spectroscopy (ARPES) or momentum microscopy.
Here, we describe how a surface-science research ecosystem centred on ARPES can be established by integrating state-of-the-art capabilities such as molecular beam epitaxy (MBE) for thin-film growth, X-ray photoemission spectroscopy (XPS) for chemical-state analysis, and scanning probe microscopy (SPM) for real-space imaging. Materials innovation is accelerated by combining these complementary techniques, leveraging both laboratory-based and user-facility instrumentation, and developing new tools to extend commercial systems.
We will present several research scenarios focused on electronic band-structure analysis and highlight application examples involving 2D materials and topological materials.
