The strictly attractive 1/l2 interaction between steps of crystal surfaces
Using SSH model for the step structure of crystal surfaces, a strictly attractive 1/l2 energy, which originates from the quantum effect of surface atoms’ collective relaxation, was obtained for the first time and shown to generally exist between steps. The repulsive 1/l step interaction was confirme...
