Abstract

High-quality crystalline FeSe is successfully synthesized in 5 minutes by an electrochemical deposition technique via increasing the solution temperature. The synthesis of FeSe have been controlled by the applied voltage, synthesis time and pH value. The obtained samples were summarized as a phase diagram at each temperature and applied voltage. The best synthesis temperature to produce high-quality crystalline samples was found to be 70{\deg}C.
