TLDR
In this article, the Hall coefficient and conductivity of TiS2 have been measured and it has been shown that the strong temperature dependence of the conductivity is matched by a strong pressure dependence that is consistent with electron-phonon scattering.Abstract:
Measurements of the pressure dependence of the Hall coefficient and conductivity of TiS2 indicate that TiS2 is an extrinsic semiconductor. The strong temperature dependence of the conductivity is matched by a strong pressure dependence that is consistent with electron-phonon scattering. In contrast, TiSe2 is a semimetal, with a strongly pressure dependent p-d band overlap. The transition temperature of the structural phase transition in TiSe2 falls at -1.2K kbar-1.read more

Electronic Properties of Transition Metal Dichalcogenides and Their Intercalation Complexes
TL;DR: The transition metal dichalcogenides and their intercalate complexes belong to a large class of the so-called two-dimensional solids in which there is a good deal of interest at present as discussed by the authors.

Charge-density waves and superlattices in the metallic layered transition metal dichalcogenides
TL;DR: In this paper, it was shown that charge-density waves and their concomitant periodic structural distortions occur in all the 4d1/5d1 dichalcogenides and related the observed periodicities of these CDW states to the theoretical form of the parent Fermi surfaces.

Electronic properties and superlattice formation in the semimetal TiSe 2
TL;DR: In this paper, a second-order structural phase transition occurs at T =202$ K involving transverse atomic displacements with wave vector with a wave vector that is a semimetal with small impurity concentrations or deviations from stoichiometry.

Charge-Density Waves in Metallic, Layered, Transition-Metal Dichalcogenides
TL;DR: In this paper, the anomalous properties of polytypes of charge-density waves, their periodic structure distortions, and the superlattices they induce are attributed to charge density waves.

The role of charge density waves in structural transformations of 1T TaS2
TL;DR: In this article, the authors interpreted extra reflexions as arising from charge density waves coupled to periodic distortions modulating a trigonal lattice, which formed a commensurate super-lattice in 1T TaS2.
