摘要：

A single electron can be trapped by a triply coordinated single cation at a magnesium oxide surface (see picture). The resulting center, denoted MgOcorner, (H+/e- is a member of a new family of surface color centers and represents a significant advance for the concept of electron-trapping sites in solids.
