Abstract

We prepared Si emitters coated with a MOCVD $CoSi_2$ layer to improve the emission properties. The $CoSi_2$ layer was grown on Si field emitters in situ by reactive chemical-vapor deposition of cyclopentadienyl dicarbonyl cobalt at 600 ${\sim}$ $650^{\circ}C$. The $CoSi_2$ coated field emitters showed enhanced emission properties of current-voltage characteristics, which were due to the increase of emitting area from Fowler-Nordheim plot. And the emission current fluctuation decreased due to the chemically stable surface properties of $CoSi_2$.
