Acd. Barbosa et Jde. Castro, ELECTRONIC-STRUCTURE OF SUBSTITUTIONAL IMPURITIES NEAR METALLIC SURFACES, Journal of magnetism and magnetic materials, 121(1-3), 1993, pp. 167-169
The electronic structure of substitutional impurities near metallic su
rfaces is investigated. It is found that the change in the total elect
ronic energy due to the introduction of the impurity oscillates as a f
unction of the impurity position relative to the surface. The origin o
f such an effect is investigated and its possible consequences are dis
cussed.
