New insights into the interlayer transport of transition metal dichalcogenides

The ascending strategy for functionalizing layered Van der Waals materials is the manipulation of the coupling between atomic sheets to create novel tunable electronic states with exploitable properties. The responsible interactions can be sensitively tested by the interlayer charge transport, which has remained largely unexplored due to associated experimental challenges. By employing focused ion beam (FIB) microfabrication we accomplished a detailed study of the resistivity anisotropy in monocrystalline, bulk Transition Metal Dichalcogenides (TMDs) — like 1T-TaS2 and 2H-NbS2. These measurements have revealed number of surprises, which will be reported.
