Abstract
A quantum partition noise with spectral density significantly smaller than the Schottkyvalue 2qI (withq the elementarycharge and Ithe mean current) is predicted to occur in nanoscale electron emitters under theaction of strong applied electric fields. The noise suppression effect appearswhenever the transmission probabilities for highly occupied states are not smallwith respect to 1. We show that in two limiting cases: the Fowler–Nordheimregime and the Richardson–Laue–Dushman regime of electron emission,the noise recovers the full Schottky noise without the suppression effect.
