Herein, an original design of electron source based on an array of carbon nanocone bundles has been modeled. The contribution to the emission within bundles is investigated using a cold emission model based on the WKB approximation. The case of a specific bundle is presented where the geometry of the nanocones leads to a change of the main emitter as the voltage is ramped up. This change is shown to alter the linearity of usual Fowler-Nordheim analysis of the simulated I(V) data.
