Electron–electron and electron–phonon interactions are two major driving forces that stabilize various charge-ordered phases of matter. In layered compound 1T-TaS2, the intricate interplay between the two generates a Mott-insulating ground state with a
The Hall coefficient of a 1T-TaS2 single crystal was measured from 360 K to 1.4 K. An abrupt change of the sign and a hysteresis were observed in the Hall coefficient at the nearly commensurate-commensurate phase transition temperature, ca. 200 K; above this temperature the major carrier was...
The electronic evolution of doped Mott insulators has been extensively studied for decades in search of exotic physical phases. The proposed Mott insulator 1T-TaS2 provides an intriguing platform to study the electronic evolution via doping. Here we appl
Origin of the large magnetoresistance in the candidate chiral superconductor 4HbTaS2 The intriguing electronic phase diagram involving charge density wave (CDW) transitions in the $\\mathrm{Ta}{\\mathrm{S}}_{2}$ system has been widely investigated over the past decade, especially for the $1T$...
we resolve the electronic states localized on domain walls in a Mott-charge-density-wave insulator 1T-TaS2using scanning tunneling spectroscopy. We establish that the domain wall state decomposes into two nonconducting states located at the center of domain walls and edges of domains. Theoretical ca...

The quantum-spin-Hall (QSH) insulator films are characterized by a two-dimensional (2D) band gap within the film and one-dimensional (1D) metallic edge states that bridge the band gap1,2,3,4,5. The edge states are spin polarized by spin–orbit coupling in a chiral configuration relative...
