From: Gate-tuned Josephson effect on the surface of a topological insulator

Figure 1

Schematic diagram of a S / N / S Josephson junction. The two yellow blocks denote the two s-wave superconductor leads, and the central cyan block denotes a normal metal lead which is deposited on the surface of the 3D topological insulator. By the proximity effect, the s-wave superconducting pair potential is induced in the surface state of the 3D topological insulator. While a gate voltage is applied on the central normal metal lead to tune the Fermi energy.
