Treatments (heat and light) undertaken on as-deposited films.
X-ray diffractograms (a) and Raman spectra (b) of films deposited over a range of temperatures.
(a) Effect of film deposition temperature on grain size, roughness, and film thickness. Parts (b) and (c) are illustrative atomic force micrographs of films deposited at 100 and .
Electrical properties of ZnO:N films deposited at different temperatures. Mobility and carrier concentration vs deposition temperature after treatment 2 (a), and resistivity vs deposition temperature comparing samples after treatments 2 and 3. The lines are guides for the eye.
Photoconductivity normalized to the net gain in conductivity vs time in the dark at room temperature. The gradients noted in the legend were determined from a linear fit on the log-log plot for the last decade of time data.
