Class Information
Number: 257/30
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
Description: Subject matter wherein the active layer through which carrier tunnelling occurs has lower electrical conductivity than the material adjacent thereto.
