1 Jun 2022 | | Abstract: | The layered transition metal dichalcogenide compounds 1T-TaS2 and 4H-TaS2 are
well known for their exotic properties, which include charge density wave,
superconductivity, Mott transition, etc., and lately quantum spin liquid. Here,
we report the coexistence of the charge density wave and superconductivity in
6R-TaS2 a relatively less studied polymorph of this dichalcogenide TaS2.
Results of the electron microscopy, magnetization, and electrical resistivity
measurements reveal that 6R-TaS2 undergoes a charge density wave transition
around 305 K and is followed by a transition to a superconducting state around
3.5 K. The estimated Ginzburg Landau parameter suggests that this compound lies
at the extreme limit of type-II superconductivity. | | Source: | arXiv, 2206.00281 | | Services: | Forum | Review | PDF | Favorites | |
