Latest Patents

“Gate Controlled Atomic Switch” describes a switch element with three electrodes immersed in an electrolyte. A bridge made of one or more atoms connects the source and drain electrodes, and the bridge can be reversibly opened and closed. The potential applied to the third electrode, the gate, controls this connection.

The method forms the switch by repeatedly applying potential cycles between the gate and either the source or drain electrode. As the potential is increased and reduced, the conductance between the source and drain can be reproducibly switched between two levels according to the gate voltage. The supplied patent information lists this invention twice with slightly different wording.
