The Role of Transport and Tunneling Measurements in Attempts to Understand the Mechanism of High-Temperature Superconductivity
13 June 1989
The status of transport measurements, in particular of resistivity as a function of temperature will be reviewed. Linear resistivities observed in all high-t sub c materials imply weak electron-phonon coupling, and appear to rule out the conventional mechanism of superconductivity. Recent tunneling results will be reviewed as well.
