A novel two step electrochemical deposition method for the synthesis of ZnO/Cu 2 O heterojunctions is reported. ZnO nanorods were grown on seeded oxidized silicon substrates and were subsequently employed as working electrodes for the electrodeposition of Cu 2 O in the same aqueous formamide solution using Zn and Cu foils as counter-electrodes respectively. Single crystalline Cu 2 O particles grow on top of the single crystalline and vertical to the substrate ZnO nanorods. Varying the growth
