| Description | ||||||
| Abstract Pure SnO2 and Al (2 mol%, 4 mol%, 6 mol%) doped SnO2 thin film on glass substrate were successfully fabricated by using the spin coating technique. The samples were annealed at 500ºC for 1 hr. The film structures were studied by X-ray diffraction (XRD). From the XRD analysis, lattice parameters, unit cell volume and crystallite sizes of the samples are calculated. According to the x-ray diffraction spectra, the samples were formed with tetragonal structure and preferred orientation alone (110) plane. Furthermore, the XRD data, dislocation density of the samples are also calculated. The surface morphology was investigated by scanning electron microscopy (SEM). From the UV-visible spectrum, absorption coefficient and the band gap energy of the samples are evaluated. |
