The ionic Raman scattering is distinguished from the conventional Raman scattering which has been used to detect structural characteristics of 2D materials such as stacking structures28 and local bonding chemistry29. The use of pulse with the mid-infrared frequency within short duration allows the ...
splitting in single-layer MoS2 revealed by triply resonant Raman scattering. Physical Review Letters 111, 13. Alidoust, N. et al. 5, 1312 (2014). Observation of monolayer valence band spin-orbit effect and induced quantum well states in MoX2. Nat Commun 14. 15. Mak, Ross, KJ..SF.....
We have investigated the interlayer shear and breathing phonon modes in MoS$_{2}$ with pure 3R and 2H stacking order by using polarization-dependent ultralow-frequency Raman spectroscopy. We observe up to three shear branches and four breathing branches in MoS$_{2}$ with thickness from 2 to...
