The Fascinating Properties of Superconducting Materials
27:41 - 34:38 (06:57)
Superconducting materials can carry electric current without any resistance, a phenomenon that only happens at extremely low temperatures when the noise of atoms moving in the lattice is low. Josephson junction is a device made from superconducting wires separated by a gap of insulator or normal metal, enabling the study of quantum mechanics at the macroscopic scale through the Josephson effect.

At very low temperatures, the electrons in certain materials settle into a special state, where they can avoid defects and are described as being part of a macroscopic quantum state.

Summary
At very low temperatures, the electrons in certain materials settle into a special state, where they can avoid defects and are described as being part of a macroscopic quantum state. This is known as superconductivity, and it allows for amazing properties like perfect conductivity and resistance to magnetic fields.

Summary
A Josephson junction is a device composed of two superconducting wires separated by a non-superconducting material. It is not a transistor, but it allows for the propagation of super current without dissipation up to a certain point, making it a useful component for circuit engineers.
