Abstract
We study the transport properties of 3 coherently coupled quantum dots conn ected incoherently to leads. We predict a new current blockade effect to oc cur at high bias voltages exceeding the Coulomb blockade threshold. All rel evant transport processes are incorporated using a density matrix approach. We calculate the resonant current analytically for the bias regime of inte rest.
