Cd(S,Se) compounds were formed when the selenization temperature exceeded 325 ¢XC. XRD analysis reveals that the prepared films had a cubic structure. The contents of selenium ions in Cd(S,Se) films were increased with increasing reaction temperatures and duration. The band gap of Cd(S,Se) films was controlled between 2.28-1.77 eV by adjusting the selenium-ion contents. All of the synthesized films exhibited n-type characteristics, as determined from Hall effect measurement. The carrier concentration and the conductivity of CdS films were significantly promoted with the selenization process. ? 2012 Elsevier B.V. All rights reserved. |
