摘要：
The electronic transport through parallel-coupled double quantum dots with Rashba spin-orbit interaction is studied theoretically in the framework of the equation of motion of Green's function. Based on molecular state representation, the Fano interference in the conductance spectrum is readily explained. The possibility of manipulation of the Fano line shape of each spin component is explored by adjusting the Rashba spin-orbit interaction strength. It is also shown that the conductance of each spin component versus phi(R) exhibits a periodic function with the period of 4 pi. The Fano resonance retains even though the intradot Coulomb interaction is considered. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
