Planar Electron

ABSTRACTA planar electron emitter was fabricated employing chemical vapor deposited (CVD) diamond thin films. This device is composed of CVD diamond films selectively deposited on a pair of patterned Au/Cr films separated 2 micrometers from each other. When the driving voltage (Vd) was applied between the Au/Cr films, the extremely low threshold emission from diamond film was observed (Vd ∼ 10 V). Furthermore, by applying high voltage on anode screen placed above this device, part of emitted current was drawn to the anode and the luminescence from phosphors was clearly seen under Vd = 50V. The mechanism of electron emission from the diamond films used in this device was also discussed by comparing with the electron emission from isolated diamond particles. It was found that the effective work functions differ between the isolated particles and the continuous films. This result suggests a difference in the emission site of electrons.

Successful Observation

ABSTRACTElectric field of less than 5 V/μm is enough to extract electrons from diamond, whereas field of one to two orders of magnitude higher is needed to extract electrons from metal emitter tips. Despite such low-threshold field, the difficulty in clarification of electron emission mechanism is the factor preventing diamond from being used in a practical use. Quite a few numbers of possible mechanisms were proposed to better understand the origin and properties of the observed emission. Most of these mechanisms were, however, based on the conventional I (Emission current)-V (Anode voltage) characteristics. Energy distribution of the field-emitted electrons is essential in direct clarification of the mechanism. In this study, combined XPS/UPS/FES system was used to characterize the electron emission mechanism of doped chemical vapor deposited (CVD) diamond. The results indicated successful observation of the origin of field-emitted electrons from doped CVD diamond comparison with natural diamond, used as a reference.
