Two Dimensional Multigap Superconductivity in Bulk 2H-TaSSe
arXiv:2207.11064 · doi:10.1103/PhysRevB.106.134515
Abstract
Superconducting transition metal dichalcogenides emerged as a prime candidate for topological superconductivity. This work presents a detailed investigation of superconducting and transport properties on 2H-TaSeS single crystals using magnetization, transport, and specific heat measurements. These measurements suggest multigap anisotropic superconductivity with the upper critical field, breaking Pauli limiting field in both in-plane and out-of-plane directions. The angle dependence of the upper critical field suggests 2-dimensional superconducting nature in bulk 2H- TaSeS.
