Kinetically-controlled synthesis of wafer-scale quasi-1D W6Te6.

Caption

Schematic comparison of reaction pathways: direct tellurization of W proceeds directly to WTe2, while the two-step WS₂-template anion-exchange strategy enables kinetic trapping of metastable W6Te6. Atomic-resolution high-angle annular dark-field (HAADF) images provide direct visualization of the W6Te6 structure. Guided by the growth phase diagram, the method enables synthesis of a 1-inch wafer-scale W6Te6 film. Raman point-mapping across the entire wafer reveals highly uniform and consistent W6Te6 spectral signatures, confirming macroscopic homogeneity.
