Resumen:
An ab initio all-electron cluster model calculation of the adsorption of alkali metals on the Si(111) surface has been performed to study the nature of the M-Si bond. It has been found to have a complex bonding nature that cannot be characterized as either ionic or covalent. Bonding energies, equilibrium distances, populations and charge densities are analysed for Li, Na, K and Rb.
