Ultrafast nano-imaging of dark excitons
David Schmitt, Jan Philipp Bange, Wiebke Bennecke +15
The role and impact of spatial heterogeneity in two-dimensional quantum materials represents one of the major research quests regarding the future application of these materials in…
Direct visualization of hybrid excitons in van der Waals heterostructures
Giuseppe Meneghini, Marcel Reutzel, Stefan Mathias +2
Van der Waals heterostructures show fascinating physics including trapped moire exciton states, anomalous moire exciton transport, generalized Wigner crystals, etc. Bilayers of tra…
Ultrafast dynamics of bright and dark excitons in monolayer WSe and heterobilayer WSe/MoS
Jan Philipp Bange, Paul Werner, David Schmitt +15
The energy landscape of optical excitations in mono- and few-layer transition metal dichalcogenides (TMDs) is dominated by optically bright and dark excitons. These excitons can be…
Probing correlations in the exciton landscape of a moiré heterostructure
Jan Philipp Bange, David Schmitt, Wiebke Bennecke +13
Excitons are two-particle correlated bound states that are formed due to Coulomb interaction between single-particle holes and electrons. In the solid-state, cooperative interactio…
