Class Information
Number: 257/29
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) > Ballistic transport device (e.g., hot electron transistor)
Description: Subject matter in which an active layer is present through which carriers pass, which active layer is thinner than the mean free path of the carriers in the material in that layer, so that carriers can pass through the layer without scattering.
