摘要

This letter reports the development of Fe-doped ZnO (FZO) nanorods via a low-temperature hydrothermal method and the fabrication of FZO nanorod metal-semiconductor-metal (MSM) photodetector (PD). The average length and diameter of the FZO nanorods were 4.5 μm and ~100 nm, respectively. The ultraviolet-to-visible rejection ratio of the sample was ~23 when biased at 1 V, and the fabricated PD was visible-blind with a sharp cut-off at 375 nm. Furthermore, the noise equivalent power and detectivity of the fabricated FZO nanorod MSM PD were 6.27 × 10^-10 W and 2.12 × 1010 cm.Hz^0.5·W^-1, respectively.
