A multi-terminal electrically actuated switch comprises a source electrode, a drain electrode, and an active region physically connected to both electrodes. The active region comprises at least one primary active region comprising at least one material that can be doped or undoped to change its electrical conductivity, and a secondary active region comprising at least one material for providing a source/sink of ionic species that act as dopants for the primary active region(s). A gate electrode is physically connected to the source/sink region. Methods of operating the switch are also provided. |
