4Hb-TaS2 has been proposed to possess unconventional superconductivity with broken time-reversal symmetry due to distinctive layered structure, featuring a heterojunction between a 2D triangular Mott insulator and a charge-density wave metal. However, since a frustrated spin state in the correlated ...
Thus, this observation increases the likelihood of the two-component order parameter scenario in 4Hb-TaS2. Furthermore, we show thatTcis enhanced as a function of the out-of-plane field when a constant in-plane field is applied, which we explain using a two-component order-parameter.#The ...
Here, we investigate the compound 4Hb-TaS2 that interleaves the Mott-insulating state of 1T-TaS2 and the putative spin liquid it hosts together with the metallic state of 2H-TaS2 and the low-temperature superconducting phase it harbors using scanning tunneling spectroscopy. We reveal a ...
A new polymorph of the layered compound tantalum disulfide, 4Hb-TaS 2, has been prepared in single crystal form. Measurements of magnetic susceptibility, electrical resistivity, and differential heat capacity show two first order transitions at 20 and 315掳K. The 315掳K transition involves only a...
Conversely, superconductivity is induced in the 4Hb-TaS2 complex. Corresponding evidence of a large change of the density of states, negative for 2H-NbSe2 and positive for 4Hb-TaS2, was also observed upon intercalation. The transport properties of all the intercalation complexes show a ...
compound (GIC) were performed by scanning tunnelling microscopy (STM) and scanning tunnelling spectroscopy (STS) A discrimination of the surface electronic structure of the octahedral structure and of the trigonal-prismatic structure in 4Hb-TaS2 was made successfully in terms of the electronic ...
Single-phase layered nanocomposite containing 4Hb-TaS 2 and poly(ethylene oxide) [PEO] has been first synthesized by using the exfoliation–adsorption technique. It has been characterized by powder X-ray diffraction (XRD) and electrical dc resistivity measurements. As the product exhibited lattice ...

The Fermi surfaces of 1 T -VSe 2 and 4 Hb -TaS 2 are calculated. The projection of the Fermi surface parallel to the layers is particularly large in the former compound and small in the latter. The first effect, which is somewhat accidental, should be tested experimentally; the second ...
The layered compounds 2H‐NbSe2, 4Hb‐TaS2, and 1T‐TaS2have been intercalated with organic molecules; and the resulting crystal structure, heat capacity, conductivity, and superconductivity have been studied. The coordination in the disulfide layers was found to be unchanged in...
