Since the first days of high-T c superconductivity, the materials science and the physics of
grain boundaries in superconducting compounds have developed into fascinating fields of …

Recent studies on high-T c superconductors have aroused new interest in tunnelling effects
in unconventional superconductors. Unlike in conventional s-wave superconductors, the d …

Unconventional superconductivity (or superconductivity with a nontrivial Cooper pairing) is
believed to exist in many heavy-fermion materials as well as in high temperature …

Van-der-Waals assembly enables the fabrication of novel Josephson junctions featuring an
atomically sharp interface between two exfoliated and relatively twisted Bi 2 Sr 2 CaCu 2 O …

An analytical formula for the dc Josephson current in anisotropic singlet superconductor/
insulator/anisotropic singlet superconductor junctions is presented. The formula is …

The formation of bound states at surfaces of materials with an energy gap in the bulk
electron spectrum is a well known physical phenomenon. At superconductor surfaces …

A general formula for the Josephson current in a d-wave/insulator/d-wave-superconductor
junction is presented by taking account of the zero-energy states formed around the …

This article is an overview of recent experimental and theoretical work on transport in phase-
coherent hybrid nanostructures, with particular emphasis on dc electrical conduction. A …

This review is an up-to-date snapshot of the current situation in studies of materials with
competing electron spectrum instabilities, namely Cooper pairing, on the one hand, and …
