Abstract
Zinc oxide (ZnO) thin films are playing several important roles in the recent development of science and technology. In the present paper ZnO thin films, undoped as well as calcium (Ca) doped, are deposited by sol-gel spin coating method. The films are polycrystalline and highly transparent. The dielectric constants, real and imaginary part both, of the films are investigated. The imaginary part is found to decrease with increase in Ca fraction indicating the decrement of free carriers in ZnO films.
