Abstract

We consider the drift of a Brownian particle in a periodic potential of the substrate under the stationary force longitudinal to the surface (passive transport) and under a variable force with the zero mean value (active transport), taking into account inertial effects. Calculations of the average velocity and the effective diffusion coefficient indicate that inertial effects always play a destructive role in the passive transport of nanoparticles, whereas in the case of active transport they may increase the average velocity and play a constructive role in the high-temperature region when the thermal energy of the particle is larger than the energy barrier of the near-surface potential.
