摘要：

We propose a simple classical concept of nanodevices working in an absolute negative mobility (ANM) regime: the minimal spatial asymmetry required for ANM to occur is embedded in the geometry of the transported particle, rather than in the channel design. This allows for a tremendous simplification of device engineering, thus paving the way toward practical implementations of ANM. Operating conditions and performance of our model device are investigated, both numerically and analytically.
