Annotation
Misfit layer transition-metal dichalcogenide (TMD) have been an intrinsically non-centrosymmetric systems. We have shown [1-3] that such 3D materials can feature interlayer conductivity, while retaining the properties of fully two dimensional TMDs, including Ising superconductivity. Misfit layer TMDs are natural superlattices based on alternations of rocksalt chalcogenide layer with quadratic symmetry (Q) and hexagonal (H) TMD with variable stacking. Strong spin–orbit coupling, and built-in inversion breaking are combined. Charge transfer between Q and H layers, out-of-plane and in-plane anisotropy in normals and superconducting state and non reciprocal transport of supercurrent (superconducting diode effect) will be studied.
