Class Information
Number: 257/104
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Tunneling pn junction (e.g., esaki diode) device
Description: Subject matter wherein the active solid-state device includes a heavily doped pn junction where conduction occurs through the junction potential barrier due to a quantum mechanical effect even though the carriers which tunnel through the potential barrier do not have enough energy to overcome the barrier potential.
