Unidirectional Alignment of AgCN Microwires on Distorted Transition Metal Dichalcogenide Crystals

Van der Waals epitaxy on the surface of two-dimensional (2D) layered crystals has gained significant research interest for assembly well-ordered nanostructures and fabrication vertical heterostructures based 2D crystals. Although van epitaxial hexagonal phase transition metal dichalcogenides (TMDCs) been relatively well characterized, a comparable study distorted octahedral (1T? or Td) TMDCs is largely lacking. Here, we investigate behavior one-dimensional (1D) AgCN microwires various TMDC crystals, namely 1T?-MoTe2, Td-WTe2, 1T?-ReS2. The unidirectional alignment chains observed these reflecting symmetry underlying TMDCs. Polarized Raman spectroscopy transmission electron microscopy directly confirm that display remarkable along chain directions can be attributed to favorable adsorption configurations 1D substrate distortion, which supported by our theoretical calculations observation similar from different cyanide chains. aligned harnessed as facile markers identify polymorphs crystal orientations
