a 2H-MoS2 nanoflakes transferred onto diamond surface. The MEW was used as the PTM, and the initial pressure was calibrated as 0.5 GPa. b Stokes and anti-Stokes Raman spectra of 6L-MoS2 under various pressures with MEW as the PTM. The dashed lines indicate the vibrational frequencies of LB6,5, S6,3, and S6,1 modes. c Pressure-dependent Raman shifts (upper panel) and FWHM (lower panel) of S6,1, S6,3, and LB6,5 modes of 6 L MoS2 nanoflake with the MEW (red) and silicone oil (blue) media. DAC diamond anvil cell, MEW methanol-ethanol-water, PTM pressure transmitting medium.
