Tip-enhanced Raman spectroscopy (TERS) has been rapidly improved over the past decade and opened up opportunities to study phonon properties of materials at the nanometer scale. In this Letter, we report on TERS of an ultrathin MoS2 flake on a nanost

Semiconducting transition metal dichalcogenide monolayers have emerged as promising candidates for future valleytronics-based quantum information technologies. Two distinct momentum-states of tightly-bound electron-hole pairs in these materials can b

In heterobilayers consisting of different transition-metal dichalcogenide (TMDC) monolayers, optically excited electron-hole pairs can be spatially separated into the adjacent layers due to a type-II band alignment. However, they remain Coulomb corre

We control the linear polarization of emission from the coherently emitting ${K}^{+}$ and ${K}^{\ensuremath{-}}$ valleys (valley coherence) in monolayer ${\mathrm{WS}}_{2}$ with an out-of-plane magnetic field of up to 25 T. The magnetic-field-induced

Monolayers of transition metal dichalcogenides (TMDCs) feature exceptional optical properties that are dominated by excitons, tightly bound electron-hole pairs. Forming van der Waals heterostructures by deterministically stacking individual monolayer

Two-dimensional transition-metal dichalcogenides (TMDCs) have recently emerged as a promising class of materials. A fascinating aspect of these atomically thin crystals is the possibility of combining different TMDCs into heterostructures. For severa

Localized surface-plasmon resonances enable efficient coupling to proximal resonant dipole transitions. By exploiting energy transfer from metal nanoparticles to monolayers of 2D crystals we point a way to generate single photons at room temperature.

Single-layer WS2 is a direct-gap semiconductor showing strong excitonic photoluminescence features in the visible spectral range. Here, we present temperature-dependent photoluminescence measurements on mechanically exfoliated single-layer WS2, revea
