Transition metal dichalcogenide metamaterials with atomic precision

Abstract

---

Here we will discuss our novel anisotropic wet-etching method that allows scalable fabrication of TMD metamaterials with atomic precision, combined with traditional nanolithography techniques.[1] We show that TMDs can be etched along certain crystallographic axes, such that the obtained edges are atomically sharp and exclusively zigzag-terminated. This allows us to fabricate interesting hexagonal nanostructures of predefined order and complexity, including a few nanometer thin nanoribbons and nanojunctions.
