文摘

A solid-state growth technique is described for the preparation of misfit layered compounds[(Bi₂Te₃)_x{(TiTe₂)_y}_1.36] from preconfigured reactants that provide independent control of both x and y. Aprocedure for optimizing the structure of the preconfigured amorphous reactants is presented demonstratingthe importance of controlling both the composition and the absolute thicknesses of the component layers.Data are presented highlighting the effect of the diffusion distances of the preconfigured reactants on thekinetics of product formation.
