Field emission from tetrahedral amorphous carbon films grown using a trigger less pulsed cathodic arc process

In this paper, we report field emission from nitrogen incorporated and as grown ta-C films grown using a pulsed trigger less unfiltered cathodic arc process. The process offers the advantage of growing ta-C films with relatively less stress, higher thickness, much lower macro particles and repeatable properties. This makes the ta-C material grown using the trigger less pulsed unfiltered arc very attractive for the field emission applications.
