Spin-dependent shot noise in aperiodic semiconductor multilayers heterostructures

摘要

We investigated the spin-dependent shot noise in aperiodic semiconductor multilayers heterostructures in the presence of the Rashba spin-orbit interaction and an electric field. The results indicate that the shot noise and Fano factor are strongly spin-dependent and can be greatly modulated not only by the external bias voltage and Rashba spin-orbit interaction but also by the thicknesses of block A and B. Our investigations may provide away to design the detection system electronic devices.
