Electrodeposition of Antimony, Tellurium and Their Alloys from Molten Acetamide Mixtures

Year: 2012

Type: article

Abstract: We examine the electrodeposition of antimony (Sb), tellurium (Te) and their alloys from molten mixtures of acetamide - antimony chloride and tellurium chloride. The binary mixtures of acetamide with SbCl 3 and TeCl 4 exhibit eutectic formation with large depressions of freezing points to below room temperature. At temperatures up to 100 °C, these mixtures are highly conductive and can be used to deposit elementary Sb and Te films at current density up to 7 A dm − 2 . Antimony telluride alloy films with composition between 20 and 81 at .% Te are obtained from ternary mixtures containing up to 0.48 M SbCl 3 and up to 0.12 M TeCl 4 . Composition of the antimony telluride films can be controlled by adjusting bath composition and current density.
