Class Information
Number: 257/9
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)
Description: Subject matter wherein the active material is a thin physical layer of material located between materials which have different electrical properties than the thin layer and wherein the thin active physical layer is (1) a potential well layer thin enough to establish discrete quantum energy levels or (2) a potential barrier layer thin enough to permit quantum mechanical tunneling or (3) a layer thin enough to permit carrier transmission therethrough with substantially no scattering of the carriers.
