Abstract

Among wide-band-gap materials, diamond has been tested extensively in many laboratories for its applicability as an electron emission material. The results are encouraging but also point out the necessity of modifying the diamond films with respect to their chemical composition and/or atomic structure. This article reports on electron emission measurements conducted on diamond coatings deposited on WC/Co alloy by a multiple pulsed laser process. The electron emission has been 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/cm2 have been calculated at an applied voltage of 3000 V (for 20 μm). We propose an explanation for electron emission.
