We report the Raman and photoluminescence spectroscopic analysis of layered MoS 2 under hydrostatic pressure up to ~30 GPa. Unlike previous studies, throughout this work, a special treatment is applied to submerge monolayer, bilayer, multilayer (~200 layers), and bulk MoS 2 samples directly into...

The present study explored the large-scale and thickness-modulated growth of atomically thin MoS2 on Si/SiO2 substrates using a two-step sputtering-CVD method. Our process exhibited wafer-scale fabrication and successful thickness modulation of MoS2 layers from monolayer (0.72 nm) to multilayer (...
This increase in bending modulus as compared to monolayer graphene is attributed, through our analytic expression, to the finite thickness of SLMoS2. Specifically, while each monolayer of S atoms contributes 1.75 eV to the bending modulus, which is similar to the 1.4 eV bending modulus of ...

It is further provided a comparison with the bulk refractive index values reported in the literature and a discussion of the difference/similarity between our work and the monolayer refractive index available from the literature, finding that the results from different techniques are in good agreement...

The reason for the largest thermal conductivity in monolayer graphene is attributed to that no scattering of in-plane flexural phonon modes [14]. A similar thickness-dependent thermal conductivity for natural MoS2 is also observed. As the layer number increases from one to three, the thermal ...
