Abstract

Stable metallic 1T‐WS2 nanoribbons with zigzag chain superlattices, highly stabilized by ammonia‐ion intercalation, are produced using a facile bottom‐up process. The atomic structure of the nanoribbons, including W–W reconstruction and W–S distorted octahedral coordination, results in distinctive electrical transport and optical Raman scattering properties that are very different from semiconducting 2H‐WS2. The correlations between structure and properties are further confirmed by theory calculations.
