Effect of Substrate Temperature and Zn Additive to CdTe Thin Films on AC Mechanism and Cole-Cole Diagram

Dr. Radhyah Mahdi Shaker Jarrah

Thin Films of pure and Zn doped CdTe have been prepared by the thermal evaporation method onto glass substrates at 500 nm film thickness. Real and imaginary () part of dielectric constant, ac conductivity (ac) and cole - cole diagram of thin films for Zn ratios (00, 0.02, 0.04, 0.06 and0.08) have been studied in different substrate temperature as a function of the frequency range (102Hz - 106 Hz). The results indicated that the dielectric constant increases with the increase of Zn concentration, but it decreases with the increase of frequency. The mechanism of Ac conductivity matches with the correlated barrier hoping model. From cole-cole diagram, the polarization and the relaxation time increase with the increase Zn concentration.
