Number: 257/215
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Field effect device > Charge transfer device
Description: Subject matter in which storage sites for packets of electric charge are induced at or below the surface of the active solid-state (semiconductor) device by an electric field applied to the device and wherein carrier potential energy per unit charge minima are established at a given storage site and such minima are transferred to one or more adjacent storage sites in a serial manner.
