Abstract :
Shot noise is the electronic noise that occurs due to the discreteness of electronic charge and has a uniform frequency spectrum. The study of shot noise suppression plays an important part in studying wave-particle duality in mesoscopic devices. Quantum partitioning at high fields leads to significant electron correlation during the tunneling process. Previous models developed to study quantum shot noise suppression have been one-dimensional (1-D) with a constant field enhancement factor. In order to take into account the geometric variation of the field enhancement factor across the surface of the emitter, a two-dimensional (2-D) model is presented in this paper.
