摘要：
Based on the embedding Green function method, we present a formula to calculate the current through a tunnel barrier. In contrast to the Landauer equation, our approach incorporates not only the contribution of propagating bulk states but also tunneling from localized states. As a first example, field emission from Cu surfaces and electronic transport in a Cu-vacuum-Cu system are presented.
