    A Simple thermally Driven Brownian Motor
    (Addis Ababa University, 2005-07) Woldu, Tesfakiros; Bekele, Mulugeta (PhD)
    In this work we study the directed motion (or current) of Brownian particles in an inhomogeneous medium due to spatially periodic temperature background, and a ratchet potential with or without load. The nature of the current in our model system is discussed in detail. In particular we analyze the behavior of the current as a function of the parameters specifying our model system such as temperature, barrier height, trap potential, load and length of hot region
