Aug 31, 2024 · Here, the authors show experimental evidence of emergent nematic Ising superconductivity with simultaneous hidden magnetism (extrinsic anomalous Hall effect and Kondo screening) in 6R-TaS2 under...

Jul 29, 2024 · The natural bulk Van der Waals heterostructure compound $6R\text{\ensuremath{-}}{\mathrm{TaS}}_{2}$ consists of alternate stacking $1T$- and $1H\text{\ensuremath{-}}{\mathrm{TaS}}_{2}$ monolayers, creating a unique system that incorporates charge-density-wave (CDW) order and superconductivity (SC) in distinct monolayers.

Jul 20, 2022 · We establish the bulk heterostructure of 1H and 1T layers in 6R phase by electron microscopy. We also show that superconductivity and CDW coexist in this bulk vdW heterostructure, and the superconducting transition temperature (2.6 K) is higher than that in both 2H (0.8 K) (16) and 1T phases of TaS 2 (1.5 K at 2.5 GPa).

Nov 15, 2023 · Here, we report the magnetic, transport and transmission electron microscopy study of the charge density wave and superconductivity in 6R-TaS 2 which is a relatively less studied polymorph of this dichalcogenide TaS 2. Our high temperature electron microscopy reveals multiple charge density wave transitions between room temperature and 660K.

Nov 1, 1975 · We have synthesized the first large single crystals of 6R-TaS 2 and determined the structural, magnetic and electronic properties. This polytype is similar to 4Hb-TaS 2 and has intrapolytypic transitions at 311 K and 15 K.

Oct 24, 2024 · The study findings show that the superconducting transition temperature (Tc) of 6R-TaS2 in the range of 0–32.5 GPa exhibits an unusual double-dome behavior as a function of pressure, with the first and second domes in the pressure range of …

Jun 1, 2022 · Here, we report the magnetic, transport and transmission electron microscopy study of the charge density wave and superconductivity in 6R-TaS2 which is a relatively less studied polymorph of this dichalcogenide TaS2. Our high temperature electron microscopy reveals multiple charge density wave transitions between room temperature and 650K.

5 days ago · The transition metal dichalcogenide 6R-TaS 2 offers a natural platform for studying the interplay among charge density wave (CDW) order, superconductivity, and transport anomalies. Recent findings reveal that, in the intermediate temperature range between charge order and superconductivity, a hidden order emerges around T ∗ superscript 𝑇 T^{*} italic_T start_POSTSUPERSCRIPT ∗ end ...

5 days ago · Notably, AHE is fully suppressed and magnetoresistance drops by 50${\%}$ within just 0.2 GPa, highlighting the fragility of the hidden order. These results reveal an unconventional superconducting pairing in 6R-TaS$_{2}$, competing with both CDW and hidden orders through weakened interlayer coupling and competition for the same electronic states.

May 6, 2022 · Here, we report a bulk vdW material consisting of superconducting 1H TaS2 monolayers interlayered with 1T TaS2 monolayers displaying charge density waves (CDW). This bulk vdW heterostructure is created by phase transition of …
