Research

We investigate atomic-scale structures, such as adsorbates or defects, and how these structures interact with each other. Using high-resolution scanning tunneling microscopy (STM) and atomic force microscopy (AFM) – techniques that routinely achieve atomic resolution – we can probe these structures and their properties with unprecedented precision.

By combining these methods with optical spectroscopy, we surpass the diffraction limit, reaching sub-nanometer spatial resolution in experiments such as STM-induced electroluminescence (STML) and tip-enhanced photoluminescence (TEPL). In addition, we are advancing these techniques toward high temporal resolution, allowing us to observe dynamic processes – such as electron motion, excited state formation and decay, and energy transfer – in nanostructures, in real space and real time.
