Nauen, A.; Hohls, F.; Könemann, J.; Haug, R.J.: Shot noise in resonant tunneling through a zero-dimensional state with a complex energy spectrum. In: Physical Review B 69 (2004), Nr. 11, 113316. DOI: https://doi.org/10.1103/PhysRevB.69.113316
We investigate the noise properties of a GaAs/AlxGa 1-xAs resonant-tunneling structure at bias voltages where the current characteristic is determined by single electron tunneling. We discuss the suppression of the shot noise in the framework of a coupled two-state system. For large bias voltages we observe super-Poissonian shot noise up to values of the Fano factor α≈ 10.
