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...
Φmono,Φmultilayer and Φtip are the work functions of monolayer MoS2, multilayer MoS2 and the surface of AFM tip, respectively (Fig. 1b). The measured surface potential difference, , corresponds to the band bending in the vacuum level Evac at thermal equilibrium and is also equal to the ...
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...
log10IIoofnf = 8.24 − 0.087t (1) It is well known that in the monolayer 2D materials, the charge carriers are confined in the 2D planes. This confinement can result in some unique characteristics not common in 3D materials, e.g. Si....
As growth is continued, at first the number of monolayer surface step lines increases only gradually with EuTe coverage. However, beyond 35 ML coverage, the areal density increases very strongly by one order of magnitude [6], indicating significant acceleration of the step formation process. In ...
To address this issue, we perform combined experimental and theoretical study on atomically thin MoS2 field effect transistors with varying the number of MoS2 layers (NLs). Experimentally, an intimate relation is observed with a 10-fold degradation in {\mu} for extremely thinned monolayer channels....
Here, we investigated the Purcell effect-enhanced PL of monolayer MoS 2 inserted in the gap of a gold nanoparticle (AuNP)鈥揳lumina (Al 2 O 3 )鈥揼old film (Au Film) structure. Under confocal illumination by a 532nm CW laser, we observed a 7-fold PL ...
