The authors have investigated the zero-frequency shot noise of current through resonant double-barrier structures. Taking into account the spin-orbit coupling (SOC) effect, general expressions for the shot noise in fully phase-coherent mesoscopic conductors are derived based on the scattering approach. It is found that the Dresselhaus SOC can greatly affect the average current I, shot noise S, and Fano factor of resonant diode structures. A large shot noise suppression with the Fano factor below 0.5 observed experimentally can be illustrated by the influence of the Dresselhaus SOC effect. (c) 2007 American Institute of Physics.
