The prospect of manipulating matter on the atomic scale has fascinated scientists for decades. This fascination may be motivated by scientific and technological...

Experimental Constraints on Some Mechanisms for High-Temperature Superconductivity

January 1, 1991

Author(s)

I Barbee, Marvin Cohen, David R. Penn

Since its discovery, many mechanisms have been suggested to explain the phenomenon of high-temperature superconductivity in oxides. We propose that experimental...
