Mutual stabilization of charge-density-wave and monoclinic distortion in sulfur at high pressures
The charge-density-wave (CDW) amplitude mode of the high-pressure sulfur-IV phase is observed between 83 and 146 GPa using Raman spectroscopy. The energy of this excitation softens with pressure yet remains finite at ν_{CDW}>100cm^{−1} up to the critical pressure, which is indicative of a weakly...
