The author reviews some of the important successes achieved by Eliashberg theory in
describing the observed superconducting properties of many conventional superconductors …

This is a revised version of the first edition published in 1991. At the same time, this is a
revised version of the Syokabo edition, which was written in Japanese and published in …

This book presents a survey of recent experimental results on copper oxide superconductors
with transition temperatures from 30 {sup 0}{Kappa} to above 120 {sup 0}{Kappa}. It …

We have measured at 4.2 and 53 K the tunneling current-voltage (I− V) characteristics of the
new high-T c superconductor Bi 4 Ca 3 Sr 3 Cu 4 O 1 6+ δ with δ= 0.32, using a low …

We have made gap measurements at 4.2 K on the high-T c superconductor YBa 2 Cu 3 O 6.
5+ x by electron tunneling using a low-temperature scanning-tunneling microscope. In all …

Tunneling spectroscopy, because of its high energy resolution in probing low lying
excitations, has been a powerful tool for investigating the mechanism of superconductivity …

An attempt has been made to summarize a large body of data dealing with measurements of
the energy gap in superconducting oxides like La 2− x Sr x CuO 4− y, YBa 2 Cu 3 O 7− y …

Since about 30 years tunneling spectroscopy has played a fundamental roˆle in determining
significant aspects of superconductivity. Recently, high-Tc superconductive ceramics have …

We have prepared thin film superconducting tunnel junctions YBa 2 Cu 3 O 7− δ/Pb of
Giaever's type and performed a study of their tunneling characteristics. Dynamic conductivity …

We report on systematic studies to perform quality controls on planar tunnel junctions
realized on high-T c superconductors (HTS). Tunneling spectra of the orthorhombic 90 K …
