Influence of interdot-coupling on differentialconductance for a triple quantum dot

Abstract

Using the method of equation of motion of nonequilibrium Green's function, we study the Aharonov-Bohm effect of differential conductance of electronic transport through a triple quantum dot system in which two quantum dots are directly coupled to the electrodes. We found that the conductance or tunneling property depends on the different values of local density of states. Moreover, electron transport through the system can be influenced by inter-dot coupling and energy level of each dot.
