Abstract

The attempt to integrate two electron transport mechanisms, by computing the field emission (FE) current as a superposition of both resonant and sequential branches, is reported. A quantum object through which the tunnelling occurs is modelled as a one-dimensional (1D) potential well separated from the substrate by a potential barrier. Results show that the proposed model is useful in the interpretation of real I-V diagrams of FE through composite vacuum interfaces and in evaluating the amount of coherence in the related tunnelling processes.
