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: 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: In this paper, a single layer of MoSe 2 encapsulated by hexagonal boron nitride can act as an electrically switchable mirror at cryogenic temperatures, reflecting up to 85% of incident light at the excitonic resonance.

TL;DR: This work demonstrates a novel method for creating high-quality heterostructures composed of atomically thin materials that allows for efficient electrical control of excitations and provides a basis for novel quantum opto-electronic devices based on manipulation of charged carriers and excitons.

TL;DR: In this paper, a single transition metal dichalcogenide monolayer of molybdenum diselenide (MoSe2) can dramatically modify light transmission near the excitonic resonance, acting as an electrically switchable mirror that reflects up to 85% of incident light at cryogenic temperatures.
