摘要：
A theoretical formalism to study the current-noise characteristic of one-dimensional double barrier heterostructures taking into account correlation effects is developed within the context of the Keldysh nonequilibrium Green functions. The effects of the Coulomb blockade on the characteristic curve (current versus voltage) and on the current fluctuation are studied in a selfconsistent calculation. For the static case a reduction of the full shot noise is observed. The effects of the barrier characteristics on the transport properties are also analyzed. A connection between the noise frequency spectrum and the transit time of the electron going along the structure is established.
