Abstract: | Using an equation-of-motion technique, we theoretically study the
Fano--Kondo effect in the T-shaped double quantum dots coupled to
two ferromagnetic leads by the Anderson Hamiltonian. We calculate
the density of states in this system with both parallel and
antiparallel lead-polarization alignments, and our results reveal
that the interdot coupling, the spin-polarized strength and the
energy level of the side coupled quantum dot greatly influence the
density of states of the central quantum dot. This system is a
possible candidate for spin valve transistors and may have potential
applications in the spintronics. |
