抄録	A recent report [Kiguchi et al., Phys. Rev. B 68, 115402 (2003)] that the (111) surface of 5 MgO layers grown epitaxially on Ag(111) becomes metallic raises a question of what will happen when we have fewer MgO layers. Here we have revealed, first experimentally with electron energy-loss spectroscopy, that MgO(111) remains metallic even when one-layer thick. We have confirmed this theoretically with the density functional theory, where metallization turns out to depend on the nature of the substrate. We finally predict, with a spin-density functional calculation, that a magnetic polar surface can be possible.
