Effect of the normal state gap on the thermoelectric power, irreversibility line and c-axis resistivity of YBa2Cu3O7-delta

We discuss the effects of the normal state gap (NSG or EG)[1] On two normal state properties, the thermoelectric power of Y0.8Ca0.2Ba2Cu3O6+x and the c-axis resistivity of YBa2Cu3O7-delta and one superconducting property, the irreversibility [2] or "vortex lattice melting" line of YBa2Cu3O7-delta. R ather surprisingly a simple Giaever tunneling model [3] seems to give a goo d description of the c-axis resistivity and the available c-axis magnetores istance data [4] for YBa2Cu3O7-delta.
