N2 - The effect of diamond-like carbon (DLC) films coated by the pulsed laser deposition technique on the electron field emission characteristics of platform-shaped Mo emitters was investigated. It was observed that DLC coatings can significantly enhance electron emission. The gate-to-cathode operating voltage (for an anode current density of 1 mA/cm2) was lowered from 50 V for uncoated platform-shaped Mo emitters to 20 V for DLC-coated platform-shaped Mo emitters. The lifetime of the DLC-coated emitters is at least twice, that of the uncoated ones. Moreover, the DLC-coated platform-shaped Mo emitters exhibited durability superior to that of the DLC-coated Spindt-type emitters, which was due to the abundance of emission sites in the platform-shaped Mo emitters.
