Class Information
Number: 257/31
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Thin active physical layer which is (1) an active potential well layer thin enough to establish discrete quantum energy levels or (2) an active barrier layer thin enough to permit quantum mechanical tunneling or (3) an active layer thin enough to permit carrier transmission with substantially no scattering (e.g., superlattice quantum well, or ballistic transport device) > Tunneling through region of reduced conductivity > Josephson
Description: Subject matter wherein the device is of the form of a pair of superconductive electrodes separated by a thin, less conductive, portion, through which superconductive tunneling may occur.
