The temperature coefficient of A1g modes in few-layered MoS2 solely and MoS2/RGO hybrid are 0.0141 and 0.0154 cm/K, respectively. The Raman vibration of E2g and A1g modes with laser powder increasing in the two samples were also measured. The qualitative analysis and comparison of the two ...

The false-color (3D type) image of the intensity of the Raman spectra of monolayer MoS2 versus both peak positions and polar angles is plotted. It shows that the strongest E2g1+ and E2g1 peaks appear at different angles, reflected as the alternation of the maxima of the intensity within ...
In this work, we experimentally investigated the dielectric effect on the Raman and photoluminescence (PL) spectra of monolayer MoS2 by comparing samples with and without HfO2 on top by atomic layer deposition (ALD). Based on considerations of the thermal, doping, strain and dielectric screening ...

Their Raman spectra are discrepant in position, width, and intensity of Raman peaks. Here, we take hexagonal boron nitride (hBN, insulator), Bi2Se3 (topological insulators), hexagonal MoS2 (2H-MoS2, in-plane isotropic semiconductors), black phphosphorus (BP, in-plane anisotropic semiconductors),...
In PMF-GERTs, 4,4′-biphenyldithiol (BPDT) Raman reporter molecules are embedded in the nanogap between the gold core and the flower-like shell, and PDA-functionalized MoS2 nanosheets (PDA/MoS2) were wrapped on the surface of the flower-shaped shell. Photothermal and photodynamic experiments ...

Stimulated Raman scattering (SRS) microscopy is a fast-growing technology with the capabilities of rapid and chemical-specific imaging of native biomolecules based on their fingerprint vibrational spectra4,5,6,7,8,9,10,11,12,13. These advantages have enabled label-free histopathology of fresh tissu...
We performed comprehensive confocal Raman and absorption mapping measurements to determine the dependence of these spectra on the stacking orientation of bilayer MoS2. The results indicated that with 532-nm laser excitation, the Raman scattering intensity gradually increased upon increasing the stacking ...
