Optical and DC electrical investigations of CuFeS2 thin films prepared by spray pyrolysis technique

الملخص EN

CuFeS2 thin films are prepared using the spray pyrolysis technique.

The effect of substrate temperature (473-713 °K) on the optical and electrical properties of the thin films is investigated.

Both optical spectra (Absorption and Reflectivity) show two electronic transitions: one is around 2.55eV and the other is around 3.65eV.

The variation of the DC electrical resistivity of the thin films is discussed in relation with the optical results and structural configuration.
