SUB- AND SUPER-POISSONIAN NOISE IN SI QUANTUM DOTS USING FULLY SELF-CONSISTENT 3D SIMULATION

摘要

The 3D Monte Carlo simulation of an Si dot-based double-tunnel junction shows not only the possibility of shot noise suppression down to the Fano factor of 0.5, but also of super-Poissonian noise. The counting statistics of the tunneling events provides a clear interpretation of the different noise regimes according to the balance between the different tunneling rates involved.
