Abstract
Some of the main anomalies in conductance characteristics of high-Tc tunnel junctions are considered. Mainly, the extreme depression of gap structures, the presence of conductance peaks in corrispondence to the counterelectrode gap, and ,,zero-bias anomalies~, will be examined. The possibility of application of the proximity Mc Millan model to describe the behaviour in conductance of high-T c junctions is considered. Discussion and preliminary comparison with experimental data on YBCO junctions are also reportedFile in questo prodotto:
