Abstract
SnO2 thin films Electron Beam Evaporation techniques prepared nanocrystalline, these films analyses by XRD, UV-Vis, and AFM. The effect of Annealing temperature shows various phases (structures and morphologies). The optical transmission (T %) in the range (190-1000) nm of films prepared was measured. SnO2 thin films show a direct allowed transition and decreased the energy bandgap from 3.75 eV before annealing to 3.62 eV and 3.27 eV after annealing. Through the results, we found that all studied characteristics were affected by the annealing process.
