Outline of Final Research Achievements

In this study, we have demonstrated the fabrication of various nanostructures using slidable atomic layers. This sliding process allowed the suspension, tearing, stacking, and connection of layered chalcogenides. Our finding provides a novel method for developing vdW heterostructures with tunable interlayer coupling and an ideal system for studying the superlubricity in incommensurate vdW contacts.
