Identification of Two Mechanisms for Current Production in a Biharmonic Flashing Electron Ratchet

The ratchet current as a function of friction applied to the electron. The ‘friction’ is the ratio of the electron relaxation time, τ_relax, to the period of oscillation (lower is higher energy input), τ_ratchet. The plot is divided into weak (left) and strong (right) friction regimes, each with their own mechanism of current production and dependence on the shape of the ratchet potential.

The current in a one-dimensional electron ratchet is controlled by the shape of the potential and the friction. Read More
