Ti-doped ZnO nanorod arrays were grown onto Si substrate using chemical bath deposition (CBD) method at 93 °C. To investigate the effect of time deposition on the morphological, and structural properties, four Ti-doped ZnO samples were prepared at various deposition periods of time (2, 3.5, 5, and 6.5 h). FESEM images displayed high-quality and uniform nanorods with a mean length strongly dependent upon deposition time; i.e. it increases for prolonged growth time. Additionally, EFTEM images reveal a strong erosion on the lateral side for the sample prepared for 6.5 h as compared to 5 h. This might be attributed to the dissolution reaction of ZnO with for prolonged growth time. XRD analysis confirms the formation of a hexagonal wurtzite-type structure for all samples with a preferred growth orientation along the c-axis direction. The (100) peak intensity was enhanced and then quenched, which might be the result of an erosion on the lateral side of nanorods as seen in EFTEM. This study confirms the important role of growth time on the morphological features of Ti-doped ZnO nanorods prepared using CBD.

“…The published values of the responsivity of different nanostructure ZnO were: 1.59 A/W at 5 V bias [35]; 0.073 A/W at 5 V bias [36]; 40 A/W at 10 V bias [37], 0.61 A/W at 8 V bias [38] and 26,000 A/W at 8 V bias [39]. Furthermore, S. M. Mohammad et al [29] report lower values of responsivity for different values of aspect ratio. The values reported were in the range of 0.00533A/W and 0.07066 A/W for aspect ratio of 4.45 and 15.21 respectively at operating voltage of 5V.…”

“…The authors controlled the aspect ratio of the ZnO nanorods via the reaction time. Furthermore, the aspect ratio of ZnO NRs was controlled through the annealing of the seed layer by S. Mohammad et al [29], they showed that the higher aspect ratio provides a higher UV responsivity and current gain. However, the results show low responsivity values compared to our study; this might be due to different approach of controlling the aspect ratio of the prepared ZnO NRs.…”

We report on the effect of the aspect ratio of zinc oxide (ZnO) nanorods (NRs) prepared via the hydrothermal process. It was found that increasing the precursor molar amount resulted in the decrease of the aspect ratio of ZnO NRs. Furthermore, the aspect ratios showed a significant effect on the structural and optical properties of the prepared ZnO NRs. The ZnO NRs were fabricated into a metal-semiconductor-metal (MSM) UV photodetector. The performances of the prepared MSM ZnO NRs were also studied and the heights aspect ratio showed that the highest responsivity had a value of 33 A/W at bias voltage of 5V and a wavelength of 380 nm. The responsivity, rise and full time of the prepared ZnO NRs showed a trend of behavior as the molar amount of the precursor was varied.
