“…It suggests that the q CDW in RbV 3 Sb 5 might have a c-axial component, leading to the significantly gapped FS along the k z direction. Similar behavior has also been observed in PdTeI with CDW vector q CDW = (0, 0, 0.396) [25] and GdSi with spin density wave (SDW) vector q SDW = (0, 0.483, 0.092) [26]. Fig.…”

We report the discovery of superconductivity and detailed normal-state physical properties of RbV3Sb5 single crystals with V kagome lattice. RbV3Sb5 single crystals show a superconducting transition at Tc ∼ 0.92 K. Meanwhile, resistivity, magnetization and heat capacity measurements indicate that it exhibits anomalies of properties at T * ∼ 102 -103 K, possibly related to the formation of charge ordering state. When T is lower than T * , the Hall coefficient RH undergoes a drastic change and sign reversal from negative to positive, which can be partially explained by the enhanced mobility of hole-type carriers. In addition, the results of quantum oscillations show that there are some very small Fermi surfaces with low effective mass, consistent with the existence of multiple highly dispersive Dirac band near the Fermi energy level.

“…The increase of Hall carrier density is related with the CDW-like phase transition near 90 K in the electrical resistivity. In general, the CDW formation induces energy band gap opening leading to the decrease of Hall carrier concentration. − However, in this case, the Hall carrier densities are increased at the temperatures below the CDW-like phase transition. The broad shoulder in electrical resistivity on the InTe 1−δ compounds is more closely related with the decrease of Hall mobility in the vicinity of the CDW-like phase transition.…”

We investigated the thermoelectric transport properties of InTe 1−δ (δ = 0.0, 0.1, and 0.2) compounds and interpreted their unusual behavior in terms of electronic and phonon band dispersions. The temperature-dependent electrical resistivity ρ(T) and Seebeck coefficient S(T) exhibit the charge density wave (CDW) transition near 87 K for InTe 1−δ (δ = 0.1 and 0.2) compounds. The CDW transitions on the Tedeficient compounds can be supported by the Fermi surface nesting along the M−X line in InTe 1−δ (δ = 0.25). The temperature-dependent Hall carrier density n H shows unusual behavior in that the n H (T) is increased by the Fermi surface reconstruction. From the temperature-dependent X-ray diffraction measurements, we found the superstructural lattice distortion at low temperatures (T ≤ 175 K), implying the intrinsic lattice instability. During the structural phase transition from tetragonal (I4/mcm) or orthorhombic (Ibam) to superstructural orthorhombic (Pbca) in InTe and Te-deficient InTe 0.8 , we observed a negative thermal expansion coefficient, giving rise to the large variation of negative Gruneisen parameters. Owing to the significant change in thermal expansion coefficients and Gruneisen parameters with respect to temperature, the energy band structure, in other words, Fermi surface, depends on the temperature, indicating a temperature-driven Lifshitz transition in InTe 1−δ compounds. The Te-deficiency induces significant anharmonicity of phonons from the numerous flat bands and negative phonon branches. The coexistences of temperature-driven Lifshitz transition, CDW formation, and lattice anharmonicity with high negative Gruneisen parameter in InTe 1−δ are very exceptional cases and suggest the profound physical properties in the compounds.

“…From many published works one can also conclude that this unusual LMR may be a common feature of CDW systems. Indeed, LMR was observed in Q1D compounds exhibiting a CDW with incomplete FS nesting such as NbSe 3 11,12 and in PdTeI 13 . Effect of LMR was reported for Q2D compounds with a CDW: transition metal dichalcogenides 2H-NbSe 2 ; 2H-TaSe 2 14 ; 1T-TaTe 2 15 , 1T-NbTe 2 16 , monophosphate tingsten bronzes (PO 2 ) 4 (WO 3 ) 2m for m=4.6 17 ; molybdenum purple bronze, K 0.9 Mo 4 O 11 and molybdenum oxides η-Mo 4 O 11 18 .…”

Linear magnetoresistance in the charge density wave state of quasi-two-dimensional rare-earth tritellurides

et al. 2017

We report measurements of the magnetoresistance in the charge density wave (CDW) state of rare-earth tritellurides, namely TbTe3 and HoTe3. The magnetic field dependence of magnetoresistance exhibits a temperature dependent crossover between a conventional quadratic law at high T and low B and an unusual linear dependence at low T and high B. We present a quite general model to explain the linear magnetoresistance taking into account the strong scattering of quasiparticles on CDW fluctuations in the vicinity of "hot spots" of the Fermi surface (FS) where the FS reconstruction is the strongest.
