A Study on the Electrodeposition Behavior of Cobalt Antimonides inCitric Based Solutions

摘要

Thermoelectric (TE) materials are attracting renewed attention for clean energyconversion. Reducing the dimension of materials to 2D/1D (e.g. thin film and nanowire) is onemajor approach to achieve high figure of merit (ZT) in the existing TE materials system.Electrodeposition has been widely used in fabricating various low dimensional TE materials.However, electrodeposition behavior of CoSb_3 skutterudites is rarely reported. In this work, we eport the co-deposition behavior of cobalt and antimony in citric based solutions by :lectrodeposition. The effects of deposition potential and concentration of cobalt and antimonycontaining precursors were studied. The focus of the study will be on the crystalline properties and chemical composition of the deposited films.
