摘要：

We report on the preparation and field-emission properties of vertically aligned conductive IrO2 nanorods. The unique geometrical features of IrO2 nanorods, including nanosized structure and self-assembled sharp tip, exhibit a strong effect on field enhancement (betasimilar to40 000), which result in a low threshold field (E(th)similar to0.7 V/mum) defined at the beginning of emission. A low turn-on field for driving a current of 10 muA/cm(2) is about 5.6 V/mum, which is comparable with the carbon nanotube, diamond, and amorphous carbon. The potential of using IrO2 nanorods as an emitter material has been demonstrated. (C) 2004 American Institute of Physics.
