Impulse Circuit Model for Single-Electron Tunneling-Zero Tunneling Time

If present, all metal islands will be considered large enough not to show energy quantization. The metal-insulator-metal structure through which the electrons tunnel is called a single-electron tunneling (SET) junction. This tunneling is considered to be stochastic, that is, successive tunneling events across a tunnel junction are uncorrelated, and is described by a Poisson process. Unless stated explicitly, tunneling through a potential barrier is considered to be non-dissipative (the tunneling process through the barrier is considered to be elastic).
