Abstract (in Japanese) (See Japanese page) 
(in English) Copper (II) oxide (CuO) and copper (I) oxide (Cu2O) films were grown on Au/Ti/Si(100) substrates by conventional chemical bath deposition (CBD) and iron (Fe)-assisted CBD methods using the aqueous solution of Cu(NO₃)₂·3H2O with pH 10, respectively. Zinc oxide (ZnO) nanorods were successfully grown on both the CuO and Cu₂O films by the CBD using the mixed aqueous solution of Zn(NO₃)₂·6H₂O and C₆H₁₂N₄. Both the PL spectra from the ZnO NRs/CuO heterostructures and those from the ZnO NRs/Cu₂O heterostructures were composed of a near-band-edge emission and a broad orange emission associated with interstitial oxygen atoms. However, current-voltage characteristics of the ZnO NRs/Cu₂O heterostructures did not show rectification behavior. This result indicates that the introduction of a buffer layer between the ZnO NRs layer and the Cu₂O (or CuO) layer is required for preventing leak current.
