Quantum melting of the charge-density-wave state in 1T-TiSe2.

چکیده
We report a Raman scattering study of low-temperature, pressure-induced melting of the charge-density-wave (CDW) phase of 1T-TiSe2. Our measurements reveal that the collapse of the CDW state occurs in three stages: (i) For P<5 kbar, the pressure dependence of the CDW amplitude mode energies and intensities are indicative of a "crystalline" CDW regime; (ii) for 525 kbar, the absence of amplitude modes reveals a metallic regime in which the CDW has melted.

Role of Incommensuration in the charge density wave and superconducting states of 1T-TiSe2
A brief review of some of the most recent experiments on the charge density wave (CDW) transition in 1T-TiSe2 is presented. With increasing pressure or intercalation, the CDW can be suppressed and a superconducting (SC) phase emerges. In the pristine 1T-TiSe2, a commensurate CDW develops around 202 K. These experiments show that by tuning these external parameters like pressure, or doping, the ...
متن کاملEvidence for an excitonic insulator phase in 1T-TiSe2.
We present a new high-resolution angle-resolved photoemission study of 1T-TiSe2 in both its room-temperature, normal phase and its low-temperature, charge-density wave phase. At low temperature the photoemission spectra are strongly modified, with large band renormalizations at high-symmetry points of the Brillouin zone and a very large transfer of spectral weight to backfolded bands. A calcula...
متن کاملNonthermal melting of a charge density wave in TiSe2.
We use time-resolved optical reflectivity and x-ray diffraction with femtosecond resolution to study the dynamics of the structural order parameter of the charge density wave phase in TiSe2. We find that the energy density required to melt the charge density wave nonthermally is substantially lower than that required for thermal suppression and is comparable to the charge density wave condensat...
متن کاملA charge-density-wave oscillator based on an integrated tantalum disulfide-boron nitride-graphene device operating at room temperature.
The charge-density-wave (CDW) phase is a macroscopic quantum state consisting of a periodic modulation of the electronic charge density accompanied by a periodic distortion of the atomic lattice in quasi-1D or layered 2D metallic crystals. Several layered transition metal dichalcogenides, including 1T-TaSe2, 1T-TaS2 and 1T-TiSe2 exhibit unusually high transition temperatures to different CDW sy...
متن کاملSuperconductivity at 2.3 K in the misfit compound (PbSe)1.16(TiSe2)2
The structural misfit compound PbSe 1.16 TiSe2 2 is reported. It is a superconductor with a Tc of 2.3 K. PbSe 1.16 TiSe2 2 derives from a parent compound, TiSe2, which shows a charge-density wave transition and no superconductivity. The crystal structure, characterized by high-resolution electron microscopy and powder x-ray diffraction, consists of two layers of 1T-TiSe2 alternating with a doub...
