摘要：

The conductance of linear arrays of two and three normal-metal small tunnel junctions is studied for bias voltages V below the Coloumb-blockade threshold. At low temperature, we find evidence for macroscopic quantum tunneling of the electric charge (q-MQT) through the Coulomb energy barrier. For double junctions the tunneling rate scales as V3, and approximately as the product of the junction conductances, as predicted by the theory of inelastic q-MQT. © 1990 The American Physical Society.
