Selective Interaction of Moving Neutral Particles with Modulated Surface and the Mechanism of Controlled Surface Nanofabrication

Abstract

It is shown that neutral particles moving above modulated surfaces undergo selective attractive or repulsive forces which in a resonance way depend on transition frequencies between internal energetic levels and the velocity of atom motion. The interaction of hydrogen atoms with surface-inhomogeneous periodic electric fields of crystallographic planes of ionic and ionic-covalent crystals is studied. It is investigated the possibility of application of such interactions for the obtaining of monochromatic by velocities one-component atom beams and also for the classication and separation of multi-component beams of particles for the determination the degree of ionicity,etc. [DOI: 10.1380/ejssnt.2014.387]
