Scalable Single-crystalline Metal Array for Tunable Emission of Van der Waals Materials

Van der Waals (vdW) materials, including h-BN and transition metal dichalcogenide (TMD), are ideal platform to explore quantum optics, Morie physics and many body effects.[1-3] Diverse applications and fundamental issues of the vdW are significant to the emission behavior and performances. Tunable emission of the vdW materials remains a long-lasting challenging issue.[4] Here, we achieved the self-assembly of the single-crystalline gold nanostructures to realize a scalable array for tunable and enhanced emission in the vdW. Synthesis, characterizations, and manipulation of the sub-100 nm single-crystalline nanostructures are presented. The scalable array is integrated with the representative vdW materials to demonstrate tunable emission and study the plasmonic effects. This study indicates that the deterministic nano-metal array is potential for quantum optics and information system.
