Here, we demonstrate the phase manipulation of two-dimensional chiral charge density waves and the design of in-plane chiral homostructures in 1T-TaS2. We use chiral Raman spectroscopy to directly monitor the chirality switching of the charge density wave鈥攔evealing a...
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
In summary, we discover distinct electronic states of domain walls of a symmetry-broken correlated insulator for the first time. The domain walls of the Mott-CDW phase of 1T-TaS2have well-localized non-metallic in-gap states along the center of domain walls and the edges of neighboring domain...
The occurrence of charge-density waves in three selected layered transition-metal dichalcogenides-1T-TaS(2), 2H-TaSe(2) and 1T-TiSe(2)-is discussed from an... Rossnagel,K - 《Journal of Physics Condensed Matter An Institute of Physics Journal》 ...
Polar charge and orbital order in 2H-TaS2 It was recently discovered that in spite of the scalar nature of its order parameter, the charge order in 1T-TiSe2 can be chiral. This is made possible by ... J Van Wezel - 《Physical Review B Condensed Matter & Materials Physics》 被引量: ...

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...
The edge states are spin polarized by spin–orbit coupling in a chiral configuration relative to the momentum and the edge normal; they are protected by time- reversal symmetry and thus robust against weak disorder. These edge conducting channels are ideally suited for low-dissipation transport of...
