Abstract

SnO 2 has been successfully grown on Si substrate using a thermal evaporation method, under different percentages of argon and oxygen gases. High purity Sn metal was used as reactants with deposition temperature were set at 900°C. Different oxygen concentrations range between 1.6 and 10% were used during thermal evaporation process. The as-prepared metal oxides were analyzed using SEM-EDS, XRD and UV-VIS. SnO 2 nanowhiskers were obtained at lower oxygen concentrations (1.6 to 6% oxygen), while nanowires structures were formed at higher oxygen percentages. XRD results revealed SnO 2 produced were highly crystalline and no other impurity phase diffraction peaks were detected. EDS analysis revealed that only Sn and O elements were present in the sample which are consistent with XRD results. UV-VIS result revealed that the optical band gap energy of the metal oxides produced have low significant effect with increasing oxygen concentration. Optical band gap energy for was within 3.3 eV, which was lower than the optical band gap energy of bulk SnO 2.
