Field Emission Properties

The sphere-like diamond microcrystalline-aggregates were fabricated by microwave plasma chemical vapor deposition (MPCVD) method. The ceramic with a Ti metal layer was used as substrates. The fabricated diamond microcrystalline aggregates were evaluated by Raman scattering spectroscopy, x-ray diffraction spectrum (XRD), scanning electron microscopy (SEM). The field emission properties were tested by using a diode structure in a vacuum. A phosphor-coated indium tin oxide (ITO) anode was used for observing and characterizing the field emission. It was found that the sphere-like diamond microcrystalline-aggregates films exhibited good electron emission properties. The turn-on field was only 0.55V/μm, and emission current density as high as 11mA/cm2 was obtained under an applied field of 2.18V/μm for the first operation. After several cycling operations, the field emission tended to stable characteristics of current versus voltage. The stability evolvement and mechanism are investigated relating to microstructure of the sphere-like diamond microcrystalline-aggregates films.

Emission Studies

With screen-printing method, the diode field emission display panel was fabricated. On the cathode back plane, the cross-like cathode electrode structure was developed for improving the field emission properties of field emission display panel. The prepared carbon nanotubes were utilized to form the electron emission sources, and the necessary cathode potential for the carbon nanotube cathode could be conducted by the indium tin oxide stripe. Seen from the fabrication pattern, the divided indium tin oxide stripe was cross-like, but the fabrication surface for the single carbon nanotube cathode pixel was circular. The whole field emission display panel possessed good field emission characteristics.

The field emission properties were tested by using a diode structure in a vacuum. A phosphor-coated indium tin oxide (ITO) anode was used for observing and characterizing the field emission. It was found that the diamond microcrystalline-aggregate array exhibited better electron emission properties. The turn-on field is only 1.1V/μm and a emission current density as high as 1mA/cm2 was obtained under an applied field of 3.3V/μm. The good field emission properties of the diamond microcrystalline-aggregate array are discussed relating to microstructure and electrical conductivity.
