“…In this case, the size increases for the concentration of 0.15 at.% and diminish slowly as the concentration rises. This behavior has been also observed by Ji et al (2010). The structural aspects presented are in accordance with the fact that a greater dopant concentration generates a higher amount of nucleation centers, and therefore there is a reduction of the crystallite size in the films.…”

“…ZnO materials can show different nanostructures, for example: nanowires, 3 nanoneedles, 6 nanoparticles, 7 and NRs. 8 Among them, the ZnO-based NRs exhibited excellent performance in device applications because of its high aspect ratio. It can be used in solar cells, light emitting diodes, PDs, and piezoelectric devices.…”

In this study, metal-semiconductor-metal (MSM) ultraviolet (UV) photodetectors (PDs) based on Cu-doped ZnO (CZO) nanorods (NRs) were fabricated and investigated. The CZO NRs were prepared on a Corning glass substrate by the chemical bath deposition (CBD) method with photolithography processes. It was found that the diameter and length of ZnO NRs increased with Cu-doped concentration. The X-ray diffraction (XRD) analysis showed that the growth of NR arrays along the c-axis was hexagonal wurtzite crystal. Compared with pure ZnO NRs, it can be seen that the main UV peak (378 nm) of photoluminescence (PL) spectra showed a blue-shift phenomenon with the increase of Cu-doped concentration. Additionally, it was found that the rise and recovery time of such a fabricated PD were shortened under the UV illumination. The UV sensing properties of the CZO PDs were improved since the trapping and de-trapping of electrons by Cu-related complexes were faster than the adsorption and desorption of oxygen molecules. With a 3 V applied bias and 380 nm UV illumination, the optimal sensitivity of our PDs is 196.6.
