Abstract

We study on electrical and light emitting characteristics of ZnO nanorods array when an electric field is applied in lateral direction to the axis of ZnO nanorods. ZnO nanorods grown on an insulator substrate are isolated with each other, i.e. there is no continuous nucleation layer of ZnO at the base of nanorods. When the applied lateral electric field is weak, no electric current and no light emission are observed. When the electric field becomes strong, however, an electric current begins to flow and bluish white light is emitted in the form of many streaks. These light streaks start from cathode and travel in all directions.
