Characterization of CBD grown ZnO films with high c-axis orientation

► Hexagonal wurtzite structured ZnO nanorods (preferred orientation along (002) plane). ► Electrical activation energies were calculated in between 0.12 and 0.15 eV. ► Microstrain and dislocation density decreased with increasing deposition time. ► Increasing deposition time was resulted in an increase in preferred orientation.
