Advanced Photoemission Studies of 2D Materials

Abstract:

Van der Waals (vdW) materials exhibit a diverse range of quantum phenomena, making them ideal platforms not only for fundamental studies, but also for next-generation electronic, optoelectronic, and energy-related applications. During this lecture, I will discuss some of the recent advancements in understanding vdW materials using angle-resolved photoemission spectroscopy (ARPES) and its extensions, including spin-resolved, time-resolved, and momentum-microscopy techniques. These approaches provide direct access to the electronic structure, spin texture, and ultrafast carrier dynamics. In particular, I will focus on key findings in transition metal dichalcogenides, black phosphorus, and cuprate superconductors. Finally, I will introduce the BALTAZAR time-resolved ARPES facility at KTH, outlining its capabilities for investigations of femtosecond electron dynamics in 2D materials with excellent energy resolution.
