ABSTRACT
We report on the preparation and field-emission properties of vertically aligned conductive IrO[sub 2] nanorods. The unique geometrical features of IrO[sub 2] nanorods, including nanosized structure and self-assembled sharp tip, exhibit a strong effect on field enhancement (β∼40 000), which result in a low threshold field (E[sub th]∼0.7 V/μm) defined at the beginning of emission. A low turn-on field for driving a current of 10 μA/cm[sup 2] is about 5.6 V/μm, which is comparable with the carbon nanotube, diamond, and amorphous carbon. The potential of using IrO[sub 2] nanorods as an emitter material has been demonstrated. © 2004 American Institute of Physics.
