ESTIMATION OF STRUCTURAL AND OPTICAL PARAMETERS FROM EDAX SPECTRA
Keywords:
CuInS, SILAR, EDAX, Lattice constants, Band gapAbstract
CuInS2 thin films have been grown onto glass substrates by novel SILAR deposition technique. The composition of the prepared films has been confirmed by EDAX spectra. From the EDAX data, the non - stoichiometry, non - molecularity, lattice constants, band gap and type of conduction has been estimated. SEM and optical transmittance spectra are employed to confirm the results of EDAXspectra. Therefore this paper is a new attempt to employ EDAX spectra to estimate the structure, optical band gap and electrical conductivity of CuInS2 thin films.
