چکیده
|
Zinc oxide is one of the most important n-type semi-conductor intensively utilized in solar cells,transparent conducting electrodes and opto-electronic devices. zinc oxide (zno) and aluminum- doped zinc oxide (azo) thin films have been deposited by the spin-coating method. their structural,optical and electrical proprieties were investigated. the x-ray diffraction shows the polycrystalline hexagonal wurtzite structure exhibiting degradation in crystallinity of elaborated films with increasing al doping concentration. this effect is reflected on optical and electrical proprieties of films. indeed,the samples present a low optical transmittance level and the band gap values between 3.17 ev and 3.20 ev. concerning the electrical properties,a decrease in the concentration of free charges carriers is observed as well as a decrease in resistivity.
