Abstract :
We have successfully synthesized FeSe films by the electrochemical deposition in the electrolyte containing FeCl2·4H2O, 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.
