Class Information
Number: 257/23
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) > Heterojunction > Quantum well > Current flow across well
Description: Subject matter wherein the device operation involves flow of carriers (electrons or holes) across the quantum well (as contrasted with tunneling through the well).
