Abstract

The globe-like diamond microcrystalline aggregates were fabricated by microwave plasma chemical vapor deposition (MPCVD) method. The ceramic with a Ti mental layer was used as substrate. The fabricated diamond was evaluated by Raman scattering spectroscopy

X-ray diffraction (XRD) spectrum

scanning electron microscope (SEM). The results led to the conclusion that the obtained film consists of crystalline diamonds structures.The field emission properties were measured by using a diode structure in vacuum. A phosphor-coated indium tin oxide (ITO) anode was used for observing and characterizing the field emission. The field emission characteristics of the fabricated diamond was studied under low electric field ( <3 V/μm) and high electric field ( <5 V/μm)

respectively. The Fowler-Nordheim (F-N) plots corresponding to the curves of the low electric field and the steady operation circles in the high electric field are almost straight line

which indicated that the mechanism of the electron emission from the diamond microcrystalline aggregate is linked to the tunnel effect. It was found that the globe-like diamond microcrystalline-aggregates exhibit good electron emission properties

but the microstructure and electrical conductivity have large change before and after the field emission. The good emission properties of the diamond aggregates could be considered to be combined results from the lots of the grain boundaries in the diamonds microcrystalline aggregates. After the field emission

the amorphous carbon become thinner and the globe-like diamonds are not damaged. When the amorphous carbon films are stable

the field emission current could be stabilized accordingly. The results indicated the globe-like diamond has excellent emission characteristics.
