| Abstract | ||
| Semiconducting CdIn2S4 thin films have been deposited by spray pyrolysis technique onto glass substrates of varied temperatures from 340°C to 420°C . Using van-der Pauw method, the variation of the electrical resistivity [(1.6*〖10〗^( 3)-0.36*〖10〗^( 3) )Ω.cm ] was found for different substrate temperatures. The as-grown layers were optically characterized in order to evaluate the optical band gaps.Optical investigations show an indirect transition (E_g^i )of (2.29-2.20)eV and an optical direct gap (E_g^d ) of (2.75-2.61)eV . | ||
