TL;DR: The SPP-based near-field spectroscopy significantly improves experimental capabilities for probing and manipulating exciton dynamics of atomically thin materials, thus opening up new avenues for realizing active metasurfaces and robust optoelectronic systems, with potential applications in information processing and communication.

TL;DR: A new contact scheme is reported that utilizes cobalt (Co) with a monolayer of hexagonal boron nitride (h-BN) that has the following two functions: modifies the work function of Co and acts as a tunneling barrier, and measures a flat-band Schottky barrier of 16 meV, which makes thin tunnel barriers upon doping the channels, and thus achieves low-T contact resistance of 3 kΩ.

TL;DR: It is demonstrated that neutral interlayer excitons can propagate across the entire sample and that their propagation can be controlled by excitation power and gate electrodes, and the electrical generation and control of excite provide a route for achieving quantum manipulation of bosonic composite particles with complete electrical tunability.

TL;DR: A van der Waals heterostructure built from atomically thin semiconducting transition metal dichalcogenides (TMDs) enables the formation of excitons from electrons and holes in distinct layers as discussed by the authors.

TL;DR: In this article, the authors report electrically tunable spin singlet and triplet exciton emission from atomically aligned transition metal dichalcogenide (TMD) heterostructures.
