摘要：
Electrodeposition is a promising low-cost method to fabricate nanostructured thermoelectric chalcogenide thin films. However, highly acidic environment (pH = 1) is always required for this kind of electrodeposition. Here we demonstrated a facile and mild electrodeposition method for binary (PbTe, Bi2Te3 and Sb2Te3) and ternary (Bi0.5Sb1.5Te3) telluride thin films with citric acid as a complexing agent. Composition and phases of these telluride films were successfully controlled by adjusting bath composition and deposition potential. The effects of synthesis conditions on the resulting microstructure and compositional homogeneity were characterized by the X-ray diffraction pattern (XRD), field emission scanning electron microscopy (FESEM) and X-ray photoelectron spectroscopy (XPS).
