摘要：

The inherently rapid ligand substitution kinetics associated with the novel and chemically compatible precursors, [MCl3((EBu2)-Bu-n)(3)] (M = Sb, Bi; E = Se, Te), enable CVD growth of ternary Bi-2(Se1-xTex)(3) and (Bi1-ySby)(2) Te-3 thin films with very good compositional, structural and morphological control, for the first time. X-ray diffraction data follow Vegard's law and Raman bands shift linearly with the atom substitutions, indicating very well-distributed solid solutions.
