隧道结不需要在金属岛中提供单电子效应。最终，隧道结可以由任意散射体代替。为了制定这一确切的条款，我们推导和分析描述任意散射体的有效作用。重要的是，即使是扩散散射体也能为单电子效应提供足够的隔离。我们还考虑了有效充电能量的波动。
Tunnel junctions are not needed to provide single electron effects in a metallic island. Eventually the tunnel junction may be replaced by an arbitrary scatterer. To formulate this in exact terms, we derive and analyze the effective action that describes an arbitrary scatterer. It is important that even a diffusive scatterer provides a sufficient isolation for single electron effects to persist. We also consider the fluctuations of the effective charging energy.
