We have successfully synthesized FeSe films by the electrochemical deposition in the electrolyte containing FeCl₂·4H ₂O, SeO₂ and Na₂SO₄. The composition ratio of Fe and Se was controlled by the synthesis voltage and pH value. The FeSe film with the composition ratio of Fe:Se=1:1 is fabricated at a voltage of -0.9 V and pH 2.1 in our electrochemical deposition. This sample has a highly crystalline tetragonal FeSe structure and exhibits a superconducting transition at 8.1 K, comparable to FeSe synthesized by other methods.
