| Abstract | |
The properties of In-doped TiO2 grown by Pulsed Laser Deposition on (1 0 0) and (3 1 1)B GaAs substrates have been investigated. X-ray diffraction and photoluminescence results have shown that samples grown on (3 1 1)B GaAs planes have better crystallographic properties than those grown on (1 0 0). Both anatase and rutile phases were detected in samples with lower In-doping (In = 5 nm) while only rutile phase was observed for higher In-doped samples (In = 15 nm). Furthermore, In-doping adversely affected the electrical properties of samples grown on (1 0 0) substrates while it enhanced those of (3 1 1)B samples. Two shallow defects were detected in all samples except for (3 1 1)B sample (In = 15 nm) where three shallow defects were observed. The presence of more shallow defects in this sample is evidenced by a red-shift in the absorption spectrum. It was concluded that sample (3 1 1)B (In = 15 nm) is best among all other samples and makes it more suitable for solar cell applications. (AU) | |
