研究了在ZnO纳米棒轴向横向施加电场时，ZnO纳米棒阵列的电学和发光特性。在绝缘体衬底上生长的ZnO纳米棒彼此隔离，即在纳米棒的基部没有连续的ZnO成核层。当施加的横向电场较弱时，观察不到电流和光发射。然而，当电场变强时，电流开始流动，并且以许多条纹的形式发射出带蓝色的白色光。这些光条纹从阴极开始，向各个方向传播。
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.
