THERMOELECTRIC PROPERTIES OF A SERIALLY COUPLED T-SHAPE-DOUBLE-QUANTUM DOT STRUCTURE

In this paper, we present our theoretical treatment for electron transport through aserially coupled T-shape-double-quantum dotstructure attached to the donor and left lead on the left side, while on the right side it is attached to the acceptor and right lead. Our treatment is based on the time-dependent Anderson-Newns Hamiltonian neglecting the correlation effects. The equations of motion are derived for all subsystems, then the steady state is considered to obtain an analytical expression for the transmission probability as a function of the system energies. The subsystems eigenvalues, the coupling interaction between them as well as the leads band width all are taken into consideration and highlighted. We employ the transmission probability to calculate the thermoelectric properties for this structure and investigate quantum interference effects on the thermoelectric properties.
