FIG. 1.

(Color online) (a) The XRD spectra of films fabricated with different (from 0 to 1 Pa) in a logarithmic scale. The symbol “*”, “○”, and “•” denotes the peaks from Si (200), ZnO (102), and ZnO (103), respectively. (b) The of films with different x. The same area (c) AFM and (d) MFM amplitude image of () film.
