photoluminescence of the dark-exciton replica in monolayer WSe2. Gate and magnetic-field dependent PL measurements unveil a circularly-polarized replica peak located below the dark exciton by 21.6 meV, equal to E″ phonon energy from Se vibrations. First-principles calculations show that the ...

The bandgaps of trilayer, bilayer, and monolayer MoS2, determined by photoluminescence, change from 1.35 to 1.65 and 1.8 eV [154], respectively. The bandgap of other typical TMDCs, such as WSe2, MoSe2 [146], WS2 [147], and GaTe [148], also increases with decreasing layer thickness, ...
In addition, PVD can maintain interface cleanliness and precisely control the film thickness in an ultra-high vacuum environment. By magnetron sputtering, Muratore et al. reported the growth of MoS2film with large-area and low-defect density where its photoluminescence intensity is comparable with ...
We demonstrate lattice polaritons, based on an open, high-quality optical cavity, with an imprinted photonic lattice strongly coupled to excitons in a WS2 monolayer. We experimentally observe the emergence of the canonical band-structure of particles in a one-dimensional lattice at room temperature,...
nanomaterial dispersions; most notably the possibility of observing solvent photoluminescence in the spectra of 2D materials such as MoS2, highlighting the need for stable solvents and exfoliation processes to minimise the influence of solvent degradation on the properties of liquid-exfoliated 2D materials...
Nanopatterning of defects in TMDCs have introduced additional functionality in 2D materials, leading to new optical and electronic devices. Chalcogen vacancies can induce sub-bandgap emission peaks and increase the overall photoluminescence intensity in TMDCs.83Optical properties of other intentionally doped...
