ABSTRACTTunneling measurements were applied to investigate the density of states of the high Tc superconductor in the temperature range from 4.2 K to the transition temperature. Several structures were found in conductance curves in higher bias region than ever reported, and they vanished around Tc. Temperature dependence of the bias voltages at which these structures appeared showed the BCS-like behavior.

Superconducting Energy Gap

ABSTRACTGiaever tunneling measurements have been applied to investigate the electronic structures of the high Tc superconductor YB2Cu3Oy near Tc. The superconducting energy gap of 17 meV was observed in V-dl/dv curve at 77 K. In the light of BCS model, 2Δ0Δ/kBTc was estimated as 3.3. Several dip structures were observed in the bias region up to 0.5 eV in V-dl/dV curve, using the 3rd derivative analysis. Through the temperature dependence, these structures were found to be associated with the superconductivity.
