Application of electron field emission from diamond grown by a multiple pulsed laser process

Abstract

The preparation and use of diamond as an electron emission material is disclosed. Satisfactory measurements were conducted on diamond coatings deposited on WC-Co alloy by a multiple pulsed laser process. The electron emission was measured in a diode configuration with a diamond surface-anode spacing of 20 and 50 μm in vacuum at P=10−7 Torr. Current densities of 6 mA/cm were calculated at an applied of voltage of 3000 V (for 20 μm). Analysis proved that electron field emission provided by a diamond grown by a multiple pulsed laser process proved to satisfactorily meet the specified demands.
