Influence of deposition time on structure and substructure of ZnO

Abstract

The methods of scanning electron microscopy, X-ray diffraction and Raman spectroscopy were used for investigation of structural features of ZnO films synthesized by chemical bath deposition from zinc nitrate and ammonia solution. X-ray and Raman studies revealed that the films are single phase and highly oriented along growth texture of [002]. Condensates have a hexagonal structure with lattice constants, of a = 0.32486 nm, c = 0.52087 nm. Coherent scattering domain size and level of microstrain were, respectively, L ~ 26 - 42 nm and ε ~ (0.59 - 3.09) 10-3 and determined by regimes of films obtaining.
