Stable Metallic 1T-WS sub(2) Nanoribbons Intercalated with Ammonia Ions: The Correlation between Structure and Electrical/Optical Properties

Stable metallic 1T-WS sub(2) 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 distinc...

Summary:Stable metallic 1T-WS sub(2) 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-WS sub(2). The correlations between structure and properties are further confirmed by theory calculations.
