Abstract

This work presents a framework for treating cold field emission that includes the effects of quantum confinement. The framework is used to generate equations predicting the emitted current density (ECD) from quantum-confined emitters of various geometries. Quantum confinement of the emitter electron supply leads to a monotonic decrease in the total ECD as the emitter dimensions decrease and as a result, the Fowler-Nordheim equation over-predicts the ECD from quantum-confined emitters.
