Bulk van der Waals Superlattice SrTa2S5 Exhibits Incommensurate Structural Modulation and Unconventional Superconductivity
The bulk van der Waals superlattice SrTa2S5 exhibits an incommensurate one-dimensional structural modulation of 2D transition metal dichalcogenide H-TaS2 layers, leading to anisotropic electronic transport and unconventional, clean-limit superconductivity with a pronounced suppression of interlayer coherence.
