DEFINITION

Classification: 505/193

Superconducting transistor (e.g., Josephson transistor, etc.):

(under subclass 191) Device or system that operates as a transistor having source, drain, and gate that includes a high temperature superconducting material as an integral portion of the transistor.

(1) Note. Usually the superconductor material comprises the source or drain having a tunneling barrier therebe-tween that is under the influence of a gate electrode that determines the operation of the device or system.
