摘要：
The nonequilibrium Keldysh Green function technique is used to study the electronic transport property of a four-quantum-dot ring system in a four-terminal configuration. A general formula for the current under dc bias is obtained; the linear conductance characteristic is numerically studied. (c) 2006 Elsevier B.V. All rights reserved.
