Abstract

In this work, zinc oxide (ZnO) nanofibers fabricated by electrospinning technique and ZnO-CuO nanofiber heterostructures UV photodetector by combining electrospinning and dip coating methods. The prepared samples were characterized by X-ray diffraction (XRD), field emission scanning electron (FESEM), and UV-visible.

 ZnO nanofiber and ZnO-CuO nanofiber heterostructures showed high selectivity in 350 nm and 410 nm, respectively. Also, the samples showed high responsivity, detectivity, and efficiency under low bias voltage and also low power density. The current-voltage (I-V) characteristics were determined under different wavelength from mercury lamp.
