Fano Effect in Transport Through a Quantum Wire with a Quantum Dot

Using the non-equilibrium green function method,the qualities of coherent electron transport in the system of quantum wire with quantum dot has been studied.Found that the linear conductance in the system of a quantum wire with a side-coupled quantum dot with two level appears very interesting phenomenon,that is,the conductance declines with conductance peak;while,for the system of two quantum dots,the linear conductance shows very interesting appearance,that is,multi-resonances.Both line styles of the conductance peaks discussed above are not the style of Lorenz because of Fano interference.
