TMD monolayers offer unrivalled superconductivity

Transition metal dichalcogenide (TMD) monolayers are promising candidates for future generations of transistors and for superconducting spintronics. The materials offer the advantage of retaining their superconducting properties even in the presence of very strong magnetic fields. Researchers at INAC dug deeper to come up with a theory to explain the phenomenon. They discovered that TMD monolayers, formed with heavy elements, present a very high intrinsic spin-orbit coupling.

However, doping the material as well as defects in the material’s crystal lattice can reduce the impact of the coupling and, thus, the material’s unrivalled capacity to withstand strong magnetic fields. In the worst-case scenario, the materials can even behave as ordinary superconductors. These theoretical findings will help researchers better assess the material’s potential future uses.
