SUMMARY

The discussion focuses on the definition and types of Josephson junctions, specifically highlighting intrinsic Josephson junctions (IJJs). An intrinsic Josephson junction is defined as the tunneling between two layers within the crystal structure, particularly in cuprate superconductors like Bi-2212, which features two CuO layers per unit cell. The charge transport is believed to occur in these CuO layers, making them critical for supercurrent flow. The standard Josephson junction involves tunneling between two separate superconductors.

The standard Josephson junction is the tunneling between two superconductors.

Intrinsic Josephson junction is the tunneling between two layers that are part of the crystal itself. In the cuprate superconductors, this is the tunneling between adjacent CuO layers for compounds having more than a single CuO layer in its structure, such as Bi-2212, which has two CuO layers per unit cell. It is believe that all the charge transport occurs in the CuO layers, so this should be where the supercurrent resides.
