SnS thin films fabricated by pulsed and normal electrochemical deposition

Abstract SnS thin films were deposited onto Sn-doped In 2 O 3 -coated glass substrates by pulsed and normal electrochemical deposition (ECD) from aqueous solutions containing SnSO 4 and Na 2 S 2 O 3 . Deposited SnS was polycrystalline and had orthorhombic structure, and its composition was S-rich. The films deposited by pulsed ECD were much denser and had smaller surface roughness than the films deposited by normal ECD.
