Class Information
Number: 257/28
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) > Non-heterojunction superlattice (e.g., doping superlattice or alternating metal and insulator layers)
Description: Subject matter wherein there are a plurality of active layers and barrier regions, the active layers being sufficiently close to each other that carrier quantum wave functions are spread out over plural active layers and the intervening barriers, and wherein the active layers and barrier regions do not form heterojunctions between different semiconductor materials.
