摘要

透射电子显微镜在室温下研究了来自同一生长批次的准一维导体 NbS3 的三个样品。缺陷较少的 1 号样品和缺陷较多的 2 号样品被确定为已知的多晶体。1 号样品和缺陷较多的 2 号样品已被确定为已知的多晶型。3 号样品是未知的多晶型。3 号样品是一种未知的多晶型，其晶格参数 c 比所有已知多晶型都要大。新多晶型的电子衍射图显示出四个卫星反射系统，这表明样品中形成了四个电荷密度波。本文讨论了形成具有更复杂结构的多晶型的可能性。

New Polytype of NbS3 Whiskers: from Simple to Complex

Three samples of a quasi-one-dimensional conductor NbS₃ from the same growth batch are studied at room temperature by transmission electron microscopy. Less defective sample no. 1 and more defective sample no. 2 have been identified as known polytypes. Sample no. 3 is an unknown polytype with the lattice parameter c larger than that in all known polytypes. Electron diffraction patterns of the new polytype demonstrate four systems of satellite reflections, which indicates the formation of four charge density waves in the sample. The possibility of the formation of polytypes with a more complex structure is discussed.
