Ratchet Effect in Surface Electromigration: Smoothing Surfaces by an ac Field
We demonstrate that for surfaces that have a nonzero Schwoebel barrier the application of an ac field parallel to the surface induces a net electromigration current that points in the descending step direction. The magnitude of the current is calculated analytically and compared with Monte Carlo simulations. Since a downhill current smoothes the surface, our results imply that the application o...
متن کاملApplication of the ratchet effect to improve material quality ( reducing vortex density in superconductors and smoothing surfaces )
Although Brownian ratchets have been conceived to describe the operation of molecular motor proteins, their basic principles are also applicable to a wide range of different physical systems. In this paper I line up two such possible applications in condensed-matter physics. The first one is the removal of vortices from superconductors. Magnetic fields frequently penetrate superconducting mater...
متن کاملHall effect in an AC electric field and related phenomena
Nonlinear Hall effect in an AC electric field and related phenomena. Abstract It has been shown that in metals and semiconductors the joint action of permanent magnetic and AC electric fields leads to arising of DC surface electric current. The physical reason for such a current is due to essentially non-linear dynamics of electronic gas in the surface layer. In adiabatic limit the analytical e...
متن کاملNear-field surface plasmon field enhancement induced by rippled surfaces
The occurrence of plasmon resonances on metallic nanometer-scale structures is an intrinsically nanoscale phenomenon, given that the two resonance conditions (i.e., negative dielectric permittivity and large free-space wavelength in comparison with system dimensions) are realized at the same time on the nanoscale. Resonances on surface metallic nanostructures are often experimentally found by p...
متن کاملInterplay between quantum dissipation and an in-plane magnetic field in the spin ratchet effect
We investigate the existence of the pure spin ratchet effect in a dissipative quasi-one-dimensional system with Rashba spin-orbit interaction. The system is additionally placed into a transverse uniform stationary in-plane magnetic field. It is shown that the effect exists at low temperatures and pure spin currents can be generated by applying an unbiased ac driving to the system. An analytical...
