| Abstract |
A new silicon clathrate compound containing barium, (Na,Ba)xSi46, becomes a type-II superconductor with a critical temperature (Tc) of about 4 K. In the compound, the silicon atoms are bonded tetrahedrally with about the same bond distances as in ordinary cubic diamond Si, but form 12- and 14-hedral cages which are linked by shared faces. The metal atoms are located in the center of the polyhedra. This is the first superconductor consisting of a Si sp3 covalent network.
