Resolving High-Energy States of Interlayer Excitons in MoSe/WSe Heterostructures
Chirag Chandrakant Palekar, Paulo E. Faria Junior, Tobias Manthei +8
High-energy states of interlayer excitons (IXs) in van der Waals heterostructures remain largely unexplored despite their importance for understanding many-body interactions and no…
An integrated all-van der Waals nanobeam laser
Aris Koulas-Simos, Pietro Metuh, Athanasios Paralikis +7
Transition-metal dichalcogenides offer a promising platform for integrated coherent light sources, yet lasing has largely relied on hybrid photonic architectures without direct qua…
Anisotropic nanoscale coherent polariton transport in CrSBr
