摘要: Well-aligned ZnO nanoflowers and nanosheets were synthesized on porous Si (PS) at different applied potentials by electrodeposition approach. The deposits grown using the optimized program characterized means of cyclic voltammetry (CV), amperometry I-t (I-t), open-circuit potentiometry. X-ray diffraction (XRD) analysis proved a strong preferential orientation (1 0 0) PS. Scanning electronic microscopy (SEM) observation showed consist with uniform grain size about 100 nm in diameter nanosheets, which may have potential applications nanodevices nanotechnologies. Thus, PS can be used as photoelectric materials due to its larger effect compared wafer according (OCP) study. Optical band gap measurements made samples UV–visible spectrophotometer thus giving 3.35 eV.
