Abstract:Injector-like nanostructure samples of ZnO, which are synthesized by hydrothermal method, are experimentally investigated for the field emission (FE) properties, especially the current density varying with the intensity of the applied electric field; and the fascinating two-stage behavior of electric field enhancement factor (β) is observed. The good performance and the two-stage behavior of the β are explained based on the combination of the intensive electric field effect in semiconductor and its influence o… Show more
