采用简单的自下而上工艺生产具有锯齿链超晶格的稳定金属 1T-WS2 纳米带，通过氨离子嵌入高度稳定。纳米带的原子结构，包括 W-W 重构和 W-S 扭曲八面体配位，导致独特的电传输和光学拉曼散射特性，与半导体 2H-WS2 有很大不同。理论计算进一步证实了结构和性能之间的相关性。
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.
