Özet:

 

The electronic and optical properties of ZnxCd (1- x)S thin films   (0.0  \le  x  \le 0.7) fabricated using the chemical spray method   have been investigated in nitrogen atmosphere. The films are deposited on   glass substrates at 420oC substrate temperature. The related optical   data are recorded in the wavelength range 200-700 nm. In addition, the   absorption coefficient is determined and correlated with the photon energy   in order to estimate the direct transition energy bandgap. The crystallite   size and degree of preferential orientation were found to decrease with the   increase of  x  and to improve upon annealing in vacuum at  \cong    600oC. The transmission edge shifted towards shorter wavelengths with   increase of x  in agreement with the expected shift in energy band gap.   The films were found to exhibit room temperature resistivity variation in   the range 100-1000 W cm with composition.
