The content discusses the exploration of unconventional superconductivity in chiral molecule-intercalated TaS2 hybrid superlattices. Chiral superconductors, which exhibit a complex superconducting order parameter that winds clockwise or anticlockwise in momentum space, represent a topologically non-trivial system with intrinsic time-reversal symmetry breaking. However, intrinsic chiral superconductors are extremely rare, with only a few examples.
The authors suggest that incorporating chiral molecules, which lack mirror or inversion symmetry, into conventional superconductor lattices could introduce non-centrosymmetry and help realize chiral superconductivity. Their studies on chiral molecule-intercalated TaS2 hybrid superlattices reveal several experimental signatures of unconventional superconductivity, including:
These findings suggest that the interplay between the crystalline atomic layers and the self-assembled chiral molecular layers may lead to the creation of exotic topological materials. The authors highlight that the hybrid superlattice approach could provide a versatile path to artificial quantum materials by combining a vast library of layered crystals with the nearly infinite variations of molecules with designable structural motifs and functional groups.
