Resumo(s)
Shot noise suppression in double barrier resonant tunnelling diodes with a
Fano factor well below the value of 0.5 is theoretically predicted. This giant
suppression is found to be a signature of the coherent transport regime and
can occur near zero temperature as a consequence of the Pauli principle or
above about 77 K as a consequence of long range Coulomb interaction. These predictions are validated by experimental data.
