- Summary:The effects of external electric field F on band gap EgD, F of ZnO nanowires (NWs) in a diameter
range of D = 0.6–2.0 nm are investigated using first-principles density-function theory for the future
application as nanogenerators. It is shown that the EgD 0) values decrease with the increasing
diameter of ZnO NWs without the electric field. Moreover, EgDF decreases with increasing of
F due to the rapid drop of conduction band maximum of ZnO NWs when D is constant. These
findings imply that EgDF functions of ZnO NWs can be modulated by manipulating D and F ,
which may be helpful for design of ZnO nanogenerators with a higher generation output voltage. - Co-author:C. He and W.X. Zhang
