Dielectric-to-metal transitions and superconductivity of new metals (Modern aspects of physical chemistry at high pressure : the 50th commemorative volume)

Abstract

Dielectric-to-metal transformations in solids under high pressure is one of more striking phenomena. The expansion of range of pressure in experiments extends the class of the substances which undergo the dielectric-to-metal transformation at high pressure. At pressures up to 200 kbar the dielectric-to-metal transitions of some elements (Ge, Si, P, Se, Te) and compounds (InSb, InAs, AISb, ZnS etc.) have been discovered. For the transformation to a metallic state of wider class of substances the new high pressure apparatus and methods of investigation are needed.
