SnS thin films fabricated by pulsed and normal electrochemical deposition

SnS thin films were deposited onto Sn-doped In2O3-coated glass substrates by pulsed and normal electrochemical deposition (ECD) from aqueous solutions containing SnSO4 and Na2S2O3. 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. (C) 2002 Published by Elsevier Science B.V.
