Contribution
It introduces a novel electrochemical method for depositing superconducting FeSe films on textured substrates, optimizing voltage to improve crystallinity and superconducting properties.
Findings
FeSe films deposited at -1.0 V show high crystallinity.
Superconducting transition observed at approximately 8.0 K.
Deposition voltage influences film composition and quality.
Abstract
FeSe film is successfully fabricated onto Rolling Assisted Biaxially Textured Substrate (RABiTS) tapes by an electrochemical deposition technique. The deposited FeSe films tend to become high crystallinity with a decrease in the applied voltage to -1.0 V, and the compositional ratio of Fe to Se approaches 1:1. The sample deposited at -1.0 V shows a superconducting transition approximately 8.0 K in the magnetic susceptibility.
