Abstract
A critical examination is presented of the vacuum-nanotriode experiment by Driskill-Smith et al. [1]. It is shown that the quantum electron device cannot be validly described with respect to a single coordinate but rather must be modeled in three dimensions. Such a model is constructed and validated using the semiclassical approximation and concepts of electron optics. It is demonstrated within this framework that the transconductance oscillations observed in the vacuum nanotriode are caused by the quantum interference of three mutually coherent electron waves within the gate aperture, the waves being produced by the field-emission tips of the cathode. It is noted that quantum-interference transconductance oscillations can occur only if the amplitude and phase of each of the three electron waves on the gate aperture, as well as electron-wave vignetting, are dependent on the gate potential.
