Abstract

Temperature is an important variable in electrochemistry, increasing the operating temperature has the capacity to provide significant increases in mass transport and electron transfer rates. In the case of electrodeposition, it can also allow the deposition of crystalline material which would otherwise be amorphous when grown at lower temperatures. In this work we exploit a high boiling point, weakly coordinating solvent, o-dichlorobenzene, to electrodeposit the p-block semiconductors antimony and antimony telluride at temperatures up to 140 °C. The effect of the temperature on the morphology and crystallinity of the deposits is investigated using scanning electron microscopy, X-ray diffraction, Raman spectroscopy and optical microscopy. An attempt is also made to rationalise the role of temperature in electrodeposition and its influence on the aforementioned properties.
