2024年8月31日 · 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...

2024年7月29日 · 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.

2023年11月15日 · 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.

2022年7月20日 · The authors have characterized powders of 6R-TaS2 by means of (a.c. and d.c.) susceptibility, resistivity, and differential scanning calorimetry. Three phase transitions were obsd. below 350 K: a superconducting transition with its onset at 2.3 K and transitions (at 80 and 325 K) that involve increases in resistivity and decreases in ...

1975年11月1日 · 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.

2024年10月24日 · 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 …

3 天之前 · 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 ...

2022年6月1日 · 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.

2024年7月31日 · The natural bulk van der Waals heterostructures compound 6R-TaS2 consists of alternate stacking 1T- and 1H-TaS2 monolayers, creating a unique system that incorporates charge-density-wave (CDW) order and superconductivity (SC) in distinct monolayers.

2024年8月2日 · 研究团队通过对6R-TaS 2 连续施加压力，在电输运测量实验中发现其超导转变温度（Tc）表现出非单调的演化：Tc先增加，随后保持不变，然后下降，最后在更高压力下反弹。
