We numerically investigate the influence of surface acoustic waves on single-electron tunneling in STM-type tunnel junctions. Surface acoustic waves (SAW's) propagate along a solid surface and periodically change the distance between STM tips and substrates. Since tunneling rates have an exponential dependence on tunneling distance, SAW strongly affects tunneling phenomena. It is found that the regularity of the SET oscillations is associated with a locking phenomenon of the tunneling distance, where the tunneling distance behaves like the Brownian motion of a particle in the tilted-washboard potential.
