Abstract
The I-V characteristics and their derivatives on the point-heterocontacts of Y(Sm)Ba 2 Cu 3 O 7−δ Cu(Ag) are presented. Three types of dependences were observed. The observed deviations from classical tunneling behavior are explained. The phonon energies were determined from the classical PC tunneling spectra.Keywords
