| Abstract | Nanotip arrays of amorphous carbon with em- bedded hexagonal diamond nanoparticles were prepared at room temperature for use as excellent field emitters by a unique combination of anodic aluminum oxide (AAO) tem- plate and filtered cathodic arc plasma (FCAP) technology. In order to avoid nanopore array formation on the AAO sur- face, an effective multi-step treatment employing anodiza- tion and pore-widening processes alternately was adopted. The nanotips were about 100 nm in width at the bottom and 150 nm in height with density up to 1010 cm−2. Transmis- sion electron microscopy investigation indicates that many nanoparticles with diameters of about 10 nm were embed- ded in the amorphous carbon matrix, which was proved to be hexagonal diamond phase by Raman spectrum and selected-area electron diffraction. There is no previous lit- erature report on the field emission properties of hexago- nal diamond and its preparation at room temperature under high-vacuum condition. The nanotip arrays with hexagonal diamond phase exhibit a low turn-on field of 0.5 V/μm and a threshold field of 3.5 V/μm at 10 mA/cm2. It is believed that the existence of hexagonal diamond phase has improved the field emission properties. |
