"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.
