Popis:	These results reflect what is believed to be the first observation of electron emission from carbon‐doped boron nitride (BN). The n‐type BN films were synthesized on n‐type polycrystalline diamond on (100)Si using reactive laser ablation. The electron emission current density measured at room temperature shows a power law dependence. Emission currents as high as 60 mA cm−2 have been measured from 150 nm thick n‐type BN films on a 24 μm n‐type polycrystalline diamond film on a (100)Si substrate. These films show a current density/applied field behavior indicative of negative electron affinity.
