Here we demonstrate that the coupling of the dark exciton and an optically silent chiral phonon enables the intrinsic 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 ...
synthesized triangular monolayer MoS2 on an SiO2/Si substrate by a hydroxide-assisted method and a MoS2/Ti3C2Tx heterostructure was obtained by a following spin-coating Ti3C2Tx suspension [129]. It should be noted that the heterostructures were randomly formed on the substrate, making it a bit ...

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...
Sensing devices are key nodes for information detection, processing, and conversion and are widely applied in different fields such as industrial production, environmental monitoring, and defense. However, increasing demand of these devices has complicat

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 ...
nm. Figure2(c)is the photoluminescence (PL) spectra obtained from the same MoS2films with vertically-aligned 2D layers in Fig.2(a) and (b). We observe that MoS2films with a thickness of <10 nm exhibit two emission peaks centered around 1.81 eV and 1.96 eV, corresponding to the...
