摘要：
We observe Coulomb blockade in the held-emission current of a metallic island between two electrodes freely suspended by thin tunneling barriers. A third electrode serves as a gating contact to trace the Coulomb staircase of the device. Coulomb blockade is revealed at 77 K in conjunction with field emission. The measurements are in very good agreement with a theoretical model, taking into account orthodox Coulomb blockade and held emission.
