Introduction(1/2)
‫ ﻪ‬The structure of the p-NiO/i-SiO2/n-ZnO nanowires (NWs)
has been proposed here to enhance the UV light sensitivity.
‫ ﻪ‬ZnO
 visible-blind nature (Eg = 3.37 eV)
 intrinsic n-type characteristics
 extensive applications in civil and military area

Introduction(1/2)
‫ ﻪ‬NiO
 wide bandgap of about 3.6 eV
 intrinsic p-type characteristics
 high chemical stability
 low-temperature process
‫ ﻪ‬The thickness effect and the role of the inserted SiO2
layer will be also discussed systematically.
