Abstract

The preparation and characterization of a large-scale of single-crystalline CuO nanoporous material on the surface of a Cu sheet by a simple thermal decomposition at 550 °C for 60 min were carried out. The field-emission scanning electron microscopy image analysis indicated that the formation of homogeneous porous CuO over Cu metal is formed, with separate parts look like islands with an inter-distance of 130 nm. Each island has a highly porous surface, in which each pore has a diameter of about 200 nm. X-ray diffraction confirmed the components of the samples with a high degree of purity have a crystalline size of 89 nm. The prepared novel Cu/CuO optoelectronic photodetector works with good efficiency for light detection under different intensity or wavelengths as the Jph values increased from 0.017 to 0.047 mA cm−2 upon rising the light power density from 25 to 100 mW cm−2. The responsivity and detectivity for the photodetector are 10 mAW−1 and 9.1 × 1010 Jones, respectively. Moreover, the photodetector has 0.25 and 0.55 s for response and recovery time for the light.
