Abstract
Transparent Zinc Oxide (ZnO) thin films having different thickness are prepared by using spray pyrolysis technique. Structural and morphological behavior has been studied by using atomic force microscopy and x-ray diffraction. The scaling behavior obtained by using height-height correlation method shows that, films with different thickness are developed under non-equilibrium condition behaves as self-affine surfaces. With the increase in thickness, the grain size as well as activation energy have found to be decreased.
