| 内容記述 | Theory of "direct" interaction, including exchange and one-electron hopping process, between a pair of atoms adsorbed on or lying near the surface, has been presented. Overlap integral of atomic orbitals of the adatoms has been taken into account. It has been shown that the exchange coupling between a pair of H atoms due to the spinflip exchange interaction in a free molecule apart from the surface is destroyed by the hopping of electrons from the metal into H atoms, and that the repulsive interaction arises from the non-spinflip exchange interaction. It is repulsive when the atomic orbitals of H atoms overlap. This explains the dissociation of H2 molecules occurring on many transition metal surfaces. Next, it has been shown that this mechanism of exchange repulsion will also occur for a pair of H atoms adsorbed at nearest neighbour sites on the surface. It leads to the sparse super structure of adlayer, such as c(2×2) structure. Numerical evaluation has confirmed it. | |||||||
