A Raman scattering study of low-temperature, pressure-induced melting of the charge-density-wave (CDW) phase of 1T-TiSe2 was reported. The measurements revealed that the collapse of the CDW state occurs in three stages. The study showed that the CDW state evolves with increasing pressure in a manner reminiscent of classical 2D melting, with crystalline and disordered CDW regimes, as well as an intermediate 'soft' CDW regime in which the CDW exhibits strong fluctuations and loses its stiffness.
