Electrochemical synthesis of iron-based superconductor FeSe films
arXiv:1111.0611 · doi:10.1143/JPSJ.81.043702
Abstract
The superconducting FeSe films were successfully fabricated using the electrochemical synthesis. The composition ratio of Fe and Se can be controlled by the electric potential and pH value. We found that the FeSe films deposited at the electric potential -1.75 V and pH 2.3 show the superconducting transition at 3.5 K. The establishment of this electrochemical synthesis technique will provide many advantages for application.
