Behaviour of the current in a two-dimensional Bttiker Landauer motor with entropic barriers 下载免费PDF全文
The behaviour of the current in a two-dimensional
Büttiker--Landauer motor, which is a position-dependent
temperature-driven Brownian motor, is investigated in the presence
of entropic and energy barriers. It is found that the motion of the
Brownian particles is influenced by the shape of the channel. The
existence of an entropic barrier can cause an asymmetric current as
the flatness ratio of the shape varies. There exists an optimized
flatness ratio (nonzero) at which the current reaches its maximum
value. 相似文献
