Exciton optics, dynamics and transport in atomically thin semiconductors
Raul Perea-Causin, Daniel Erkensten, Jamie M. Fitzgerald +4
Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This mak…
Ultrafast phonon-driven charge transfer in van der Waals heterostructures
Giuseppe Meneghini, Samuel Brem, Ermin Malic
Van der Waals heterostructures built by vertically stacked transition metal dichalcogenides (TMDs) exhibit a rich energy landscape including interlayer and intervalley excitons. Re…
Exciton transport in a moiré potential: from hopping to dispersive regime
Willy Knorr, Samuel Brem, Giuseppe Meneghini +1
The propagation of excitons in TMD monolayers has been intensively studied revealing interesting many-particle effects, such as halo formation and non-classical diffusion. Initial…
Microscopic origin of anomalous interlayer exciton transport in van der Waals heterostructures
Daniel Erkensten, Samuel Brem, Raül Perea-Causin +1
Van der Waals heterostructures constitute a platform for investigating intriguing many-body quantum phenomena. In particular, transition-metal dichalcogenide (TMD) hetero-bilayers…
Electrical tuning of moiré excitons in MoSe bilayers
Joakim Hagel, Samuel Brem, Ermin Malic
Recent advances in the field of vertically stacked 2D materials have revealed a rich exciton landscape. In particular, it has been demonstrated that out-of-plane electrical fields…
Trion-phonon interaction in atomically thin semiconductors
Raul Perea-Causin, Samuel Brem, Ermin Malic
Optical and transport properties of doped monolayer semiconductors are dominated by trions, which are three-particle compounds formed by two electrons and one hole or vice versa. I…
