Paper Abstract

A method of the quantum adsorption of atoms on a surface is proposed and experimentally implemented. The loading of atoms into a surface potential well (adsorption) was realized due to the loss of the kinetic energy in the process of the inelastic collision of two laser-excited atoms. This scheme is implemented for Rb atoms adsorbed on the surface of a YAG crystal. The dependence of the quantum adsorption rate on the laser radiation frequency is experimentally investigated. The possibility of producing microstructures of arbitrary shape that consist of atoms localized on the dielectric surface is also demonstrated and the opportunities of creation of nanostructures are discussed.
