Twist Angle Dependence of Exciton Resonances in WSe/MoSe Moiré Heterostructures
Chirag Chandrakant Palekar, Joakim Hagel, Barbara Rosa +7
Van der Waals heterostructures based on TMDC semiconducting materials have emerged as promising materials due to their spin-valley properties efficiently contrived by the stacking-…
Impact of atomic reconstruction on optical spectra of twisted TMD homobilayers
Joakim Hagel, Samuel Brem, Johannes Abelardo Pineiro +1
Twisted bilayers of transition metal dichalcogenides (TMDs) have revealed a rich exciton landscape including hybrid excitons and spatially trapped moiré excitons that dominate the…
Trion photoluminescence and trion stability in atomically thin semiconductors
Raul Perea-Causin, Samuel Brem, Ole Schmidt +1
The optical response of doped monolayer semiconductors is governed by trions, i.e. photoexcited electron-hole pairs bound to doping charges. While their photoluminescence (PL) sign…
Bosonic Delocalization of Dipolar Moiré Excitons
Samuel Brem, Ermin Malic
In superlattices of twisted semiconductor monolayers, tunable moiré potentials emerge, trapping excitons into periodic arrays. In particular, spatially separated interlayer exciton…
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…
