摘要：

We study the photovoltaic effect due to gate-voltage modulations in an asymmetric constriction. Taking a simple system as an example, we show that, under certain conditions, an integer amount of electrons per absorbed photon or per cycle can be transmitted. The interaction with the modulation occurs mainly in some resonant points along the constriction.
