"New Unconventional Superconductors and Semiconductors"
Abstract: I will review synthesis methods, basic physical properties and
some aspects of anisotropy of new intermetallic correlated electron model
materials that are currently being developed at BNL. Recently discovered 115
family of Ce - based heavy fermion superconductors will be presented in the
historical context, progressing from the discovery of 115 superconducting
family, and ending with some recent results. This will be followed by the
discovery of bulk superconductivity in quasi - 1D superconductivity in metal
chains of Nb2Se3 and colossal magnetoresistance effect in narrow gap nearly
magnetic (or "heavy fermion") semiconductor FeSb2.
