Abstract :
We observe Coulomb blockade in the field-emission current of a metallic island between two electrodes freely suspended by a thin insulating layer. The Coulomb-controlled current shows a stepwise increase in the low bias regime at 77K. The variation of the step width at different gate voltages is investigated. A theoretical model suggested by Raichev [2] explains the obtained traces, taking into account orthodox Coulomb blockade and field emission in the low bias regime.
