Amitav Sen, a comprehensive consideration of factors such as electrolyte composition, choice of electrode material, and optimization of deposition parameters (deposition time, voltage and temperature) is essential for enhancing the electrodeposition synthesis of Cu2Te. This is especially important because you've already tried making it using hydrothermal synthesis, and now you want to compare it between the two techniques.
Co-Deposition of Coating with fix stoichiometric ratio will require calculations on the individual deposition rate as a function of process parameters associated with electrodeposition (voltage, current, bath temperature, pH, concentration of salt, turbidity) then setting approximate ratio of concentration of both salts to form solution to produce coatings near to the desired stoichiometric ratio.
