Abstract

The dependence of electron field emission of CN x films on annealing temperature was examined using voltage-current measurements. The change in the chemical bonding structure induced by annealing treatment was also studied. The CN x films were deposited using magnetron sputtering in pure N 2 atmosphere. The electron field emission of CN x films was found to depend on the variations of the N content and the fraction of sp 2 clusters in the films. Optimal electron emission properties were exhibited by CN x films annealed at 750°C.
