MgB2-like Superconductivity in some of them    [PDF]

The symmetry of the Periodic Table makes it possible to predict certain properties of similar elements and compounds using one of them as a template. Magnesium diboride, MgB2, presents a useful template in the search for similar materials. Starting from electronegativity, valence electron and atomic number equivalency, we identify many potential similar materials. One of them is the beryllium silicide, Be2nSin cluster system. We establish that though not yet produced in bulk, Be2Si exists. We show from symmetry principles that beryllium silicide and some of its clusters will be MgB2-like superconductors with Tcs close to or higher than 39K.
