ARPES signatures of trions in van der Waals materials
Giuseppe Meneghini, Maja Löwe, Raul Perea-Causin +5
Angle-resolved photoemission spectroscopy (ARPES) has recently emerged as a direct probe of excitonic correlations in two-dimensional semiconductors, resolving their dispersion and…

Spatiotemporal dynamics of moiré excitons in van der Waals heterostructures
Giuseppe Meneghini, Samuel Brem, Ermin Malic
Heterostructures of transition metal dichalcogenides (TMDs) offer unique opportunities in optoelectronics due to their strong light-matter interaction and the formation of dipolar…

The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
